To much Revving

[SAllen0400]

besides the obvious boost in power, after I got my TOGs installed something else was different. If i were to floor it (rolling start), it would rev up to about 5000 without moving the car, then shift hard, then it would go. it doesn't happen all the time, but every now and then. Especially if I am already doing like 30mph, then hit it. Kinda scary sometimes. Could this mean my tranny is startin to slip?

[IanGT99]

Mine does the same damn thing....p*sses me off every time it does it. Like yours, it's only once in a while that it'll do it, but I sure wish I knew what was causing it. Whenever I put it in reverse, back up, then go to put it back into drive, I always make sure the car comes to a complete stop before I shift. It still does it sometimes, though... :rage: Anyone have any help for us???

Take it from a guy that needed a new tranny, Get It Checked. :eek:

[sicc]

something similar happens to me... when i shift from Neautral to 4 sometimes it takes like 5 seconds to actually shift. at first when i didnt notice it, i would give it gas right after shifting, and it would basically do a neutral drop because of the delay. im sure this has happened to others, and am wondering if getting the 'tranny service' from the dealership might fix this. ive been due for 1 anyway.

[PACE]

When this happened I sold my 2000 IMMEDIATLY! Mine started doing it after I used the transmission interceptor with a set of drag radials while spraying at the track.....Have either of you used the trans. interceptor?

[SAllen0400]

nope, havn't used the trans interceptor, but i have sprayed twice.

[X-ception]

mine did this before. but hasnt since I got my tranny system flushed and then refilled.

[sicc]

i have the b&m shift kit ;x

[IanGT99]

I've done nothing to my tranny. Didn't even know I needed to. Anyone recommend anything that might fix my problem and/or fortify the tranny?? What does the trans interceptor do??

[PontiacGT2K]

I wouldn't suggest flushing the tranny....it has a lot of particles in it from your transmission grinding, and for some reasons helps when it comes to friction and such. You flush that out and put in new fluid, you're bound to blow the tranny. I've seen it happen many a time. Just put a trans cooler and shift kit on it, that's about all you can do other than re-build it.

[GT2003]

Sometimes I just think our cars are a piecer. I mean I love my car. But my tranny went out before, I have gone through two power steering pumps and now the sterring column needs to be fixed. I am ****ed at how many things go wrong with our cars.

If your tranny is slipping, I dont think you want to put a shift kit on it. Correct me if im wrong, but that would make the problem WORSE?

The transmission cooler would probably help...I'd change the fluid...but thats my opinion.

[PontiacGT2K]

Well I'm here to tell you otherwise. I've had my 2000 GT since brand new...and there's a guy or two on this board to vouch for the fact that I've beat the **** out of it! 80k miles on it now...only problem I've had is Intake Manifold Gasket and Water Pump (both are known to go out on 3400's).

I took 99studlyGT for a ride in my car last night, he hadn't seen/felt the new suspension yet. He was like "damn you beat the **** out of this thing....how does it still run this well?" and i was like "i dunno...it's a GT...they're tanks IMO".

No, shift kits up line pressure, which only helps friction. One would think to the contrary, but tests prove shift kits help tranny life. Same with trans cooler. Flushing tranny has never helped a thing. My girlfriend's car, as well as 3 friends of mine, all had their auto's flushed in the past just to have it blow on them within 400 miles. The fluidity of used trans fluid is good for a trans, believe it or not.

[GrandAmGT99]

Well, I respect that, but im also on my THIRD pontiac grand am GT, two of which i have also beat on.

Your opinion is yours, mine is mine.

Id change the fluid, fresh fluid always helps keep things cool.
I would NOT add the b+m kit, or the auto trans intercepter. Anything that increases line pressure for harder shifts (like the intercepter) is NOT going to help a slipping tranny.

ahh... I see. Well, I don't know. Im just saying what I would do, Im not an expert, so Im not going to try to convince anyone otherwise. Thanks for the info. :thumbs: :D

[PontiacGT2K]

Hey that's what we're all here for...help eachother out with previous knowledge and experience. If a tranny's slipping, I personally wouldn't dump more money into it either, I'd look for new options for transmission in general. But the shift kit and cooler will both help for now.

[GrandAmGT99]

Yeah...the solution: GET A NEW TRANNY before yours dies.

[jaketuff]

Everything said is pretty much right on. The tranny may not be failing totally... but it sounds like it has reason to in some cases, especially when N20 is used.

The tranny flush and fill will most likely lead to more slipping in most cases, as you will wash out the noted particles that help the 'gears' grip.

The tranny kits, especially the AT Interceptor should help a lot to improve friction and eliminate some slippage. The issue is that the car will adjust to the AT Int, and it will reduce the tranny's PCM based line pressure to compensate. The car is hardcoded to granny shift and it will adapt to do so - but you can reset the PCM to keep the shifts hard.

I flushed and filled my tranny with fluid when I started to notice 3rd gear slipping... it killed my MPG and you could really feel the unit slip. With the AT Interceptor I got a lot of grip and MPG back. But not enough to make the thing worth keeping. I have a cooler etc on there as well. My tranny blew after 70k.

In retrospect, I should not have changed the fluid, and I should have just put on the AT interceptor. In my case remember I lost 3rd gear, MPG fell off considerably b/c OD took so long to engage. And the car was sluggish - it was probably a mid 15 in the 1/4 mile as opposed to a a mid/high 14, so not TOO sluggish.

If your MPG are way off, and the tranny slips into 1st, and you have beat on it... your 45 is probably failing/ed. If it will shift properly and only occasionally slip, and you are out of warranty... I would up the Line Pressure with the AT Int, and be happy with that while saving for a new/used 45 if it really gets poor MPG.

[Jagey]

My car occaisonally shifts super hard when going from park to drive, or park to reverse. Is this a slipping tranny, or am I not waiting long enough for the tranny to get into gear before taking off?

[BLEE]

if the car is still under warranty, will they fix the problem if the tranny is slipping?

[PACE]

They will blame you for the transmission failure......or at least try.

[PontiacGT2K]

That's why you take everything off the car that would lead them to suspect you added power (ie nitrous) and play dumb.

It's very hard to say, b/c nobody can tell what "super hard" feels like to you... If your car shudders when it shifts into gear then there may be an issue. Remember to take your time placing it into gear... never reverse the car and and coast and then pop it in drive - always come to a FULL stop before placing the car into D from reverse.

Try to stab the brake when shifting into D as well. Meaning, to release the car from park you need to step on the brake... once you are out of park (and it is of course safe to do so) ease of the brake and let the car catch D and move ahead when it does so. This can help keep the tranny from being further worn... however much - it helps.

If you don't notice the "super hard" sensation going away then you may have a problem. If you have the interceptor turned up and isntalled... I just wasted a lot of time.:eek:

JOUT

[IanGT99]

My car did the tranny slipping thing again today... :rage: Do you guys think I should get it looked at?

[PontiacGT2K]

Yeah get it checked. Whatever you do don't change the trans fluid...that's when you'll blow your trans.

[Blackrider]

I though my tranny was slipping to but it was just wheel sping :eek:

[PontiacGT2K]

Haha...I experienced a lot of that last night. Raced (at a 1/4 track of course....;) ) a del sol, didn't even spray on him and spun all the way through 1st gear, into second.

[Blackrider]

I just sping p to aboyt 5500 then it grips and goes.

[IrateSpeed6]

I don't know how you guys talk about spinning the tires through first gear into second... my car never did that when it was close to stock...

[Blackrider]

Mine isent close to stock. Thats and I am using Cooper cobra GTZ's:rolleyes:

http://www.theweathernetwork.com/weather/cities/can/pages/CAMB0244.htm

Also look at the weather hear thease day Its Really cold for this time of year.

When Its warmer if I Launch right I can hook pretty good but the coopers are a true all Season. They dont grip worth a ****.

[PontiacGT2K]

And since when was Blackrider or I really close to stock? I know we don't have boost....but I think esp. in Blackriders' case, it doesn't matter, he's got enuf power to romp some of the guys with just the s/c.

And Blackriders' got headwork done.....he'll be putting up better times than I will.

One thing you guys have got to understand is just because you have boost doesn't mean you know how to make a car perform. If you have lots of pressure being pushed into that intake manifold, yet nowhere for it to go because your heads, exhaust manifolds, and borla (cough close to stock flow cough) exhaust are all restrictive as hell, then air's not moving through there like it should.....it's just not efficient.

Restrictive as Hell, NOT. Stock Flow, I don't think so! Maybe you should check my 'N-Body Thingee'. I don't claim to be a 'Performance Guru', but there are different ways to achieve 'High Performance'. You can go the N/A route or you can go Boost(Turbo or SC). I respect anyone who can make this GA perform, whether it be NA or Boost. Lastly, Engines 101 is a course you need to take, before you speak again about what is restrictive or efficient.:wave:

[PontiacGT2K]

A certain member of the board (Aleroboy) opened up the Borla muffler, and confirmed that it was entirely restrictive inside.

And I do respect anyone who mods the car, either route they take. But if I state a fact, like "Some of the NA guys are as fast as some of the boost guys", you shouldn't get all upset about it, you're just mad because it's true.

It's good to know N/A work can be just as effective as an SC. I chose the SC, because it is the one single 'Bolt-On' that can deliver 75 extra HP and a boatload of torque. No other single 'Bolt-On' can match it(other than Turbo). I am finished performance modding, because it gets too expensive for every step up in HP. I applaud you and all other modders who choose the N/A route. I am happy with my ride and I have taken it as far as I want to go. I always keep this in mind, 'No matter how fast you think your car is, there are many cars out there that are faster'. Next time I will start with a car that is fast from the factory.:thumbs: :)

[coupe]

Kman dont worry about him. He told me SLP is restrictive also. He said it aint straight through muffler. Yet when i looked into the muffler there is very little if anything in there. Its not restrictive at all.

[PontiacGT2K]

coupe: I said the SLP muffler is more restrictive than the Magnaflow straight-through muffler.....you compare then side by side like I did and then tell me otherwise. Open up the SLP muffler, and tell me otherwise. It's got a swiss cheese mesh plate, as well as other things that keep air from flowing through like it should, and it dooesn't distribute the gas 50/50 like it should.

Now....I'm not saying the SLP muffler is horrible, I'm saying there's room for improvement by getting a different muffler to replace it with.

[SC/TGrandAm]

why arent you a damn nascar mechanic or something?? With all this talk coming from you, id estimate that you was...

I dont do preformance or know much about it but some of the stuff coming from you sounds far-fetched if you know what I mean unless you back up what you say with cold hard facts.

[PontiacGT2K]

.....back up what you say with cold hard facts. ..... I'm almost positive I took pics of the inside of the SLP before I shipped it out. When I get home, I'll post them.

But it's not like I'm saying Mars is purple, I'm saying the SLP muffler has swiss-cheese grating in it. Ask anyone who's looked into it, they'll say the same thing.

Now, look into the Magnaflow muffler. There's nothing, but a splitter for exhaust to go 50/50 into each outlet.

Hey, you call me out, I can call you out. Especially when:

A.) What I'm saying is cold hard facts, that is common knowledge amongst the "nascar mechanics" here on the site.

B.) You're talking about something you don't know much about.

[SC/TGrandAm]

Well im not talking about the muffler first of all so assume that, I could careless about the muffler i believe you on that. Im talking about all of your other posts, you have become quite the engine "guru" lately and i was wondering why. I thought maybe you graduated from rocket science 101 or something.

And I dont have to know everything there is to know about engines to realize some of the things you say are far-fetched. I think maybe KMan has pointed out some of your misinformed things?

The only thing KMan and I have disputed was whether or not the Borla was a restrictive setup. Esp. with headers, the Borla doesn't add up right. 2.25" piping connected to 2.5" piping?! It's common sense that there'll be a bottle neck.

I never claimed to know everything about engines. I know didly squat about a lot of things. But what I speak about, I know about.

[Blackrider]

I hope your not going to put your N/A Hopes and dreams on me, because tomorrow is going to be Cold and I'm not to sure how good I'm going to hook up. I'm going to be at the track tomorrow with Mazda Proto with better rubber on them thanks to a boddy on mine. I hope to brake 14's tomorrow it all depends on track conditions.

[IrateSpeed6]

You can't tell the flow of a muffler just by looking at the baffles. You would be amazed at how reflected pulses and sound cancellation baffles can change the flow of an apparent "straight through" muffler.

Try to take it a little easy guys... go get some flow numbers then argue. :thumbs:

When ya convey info like this you should be a little nicer about how ya tell the info and not be a all knowing jerk off. My 2 pennies.
