Ok So over the past few months my car has been a dog shifting into second I mean it take 1-2 seconds to complete the shift. It only happends when it is warm. it shifts fine when it is cold. Now i was talking to Seth (Iceman) and he said he has been having the same problem. There is a Possible TSB on the issue sound like a shift solinoied. anyone elce having this problem. Dave I'm looking in your direction.

I have the same problem.I am interested as well in finding a fix.

had the same problem on mine, got an autotrans interceptor, set the value just a little higher then stock and the problem went away. Seems like too little tranny fluid pressure to move the solenoid..i guess maybe a little oil or dirl build up around the solenoid or something, but since i put my ati i have had no problems at all

im at 90k on my car and have the same problem. When shifting to 2nd, it kinda feels like your driving a stick shift. Ive posted several threads and most people said theres does that also and its just a sloppy GM thing. ??

when i had this prob about 2 years ago, i purchased the b&m shift kit [for the performance, not to try to fix it] and i noticed it go away after a while. ive also noticed the computer seems to adjust after using the shift kit a few times. i noticed when i didnt have it on, i would still get pretty firm and quicc shifts... im not suggesting this as a fix at all, cuz in most cases it could make the situation a lot worse, but it seemed to just be a line pressure case for my GA.

My line pressure is up with the DHP and it never did it before.. so I'm thinkin mechanical probs... I gotta call the trans shop later and see what they have to say.

No wonder you ran so slow man, that shift is like 3 seconds long!

Hey, bro...just saw this thread. That's worse than mine ever was. I think in all my tinkering around with it, the worse it ever got was about .9 seconds. If I had to guess I'd agree with Iceman that it's something mechanical, and most liekly the 1-2 shift solenoid. Good luck with it man. It's about time for you to get a new pb at the track!

I had the same problem. But after I unplugged the battery, it went away. But I have a new problem now. When I accerate slow, when it shifts from 2-3 or 3-4, the RPM just bounces up and down and it would only shift when I give it more gas. Is this related to solinoid? How hard is it to replace this? It started doing it when I got my intake.

At approximately 15,000 miles my SES light came on...and it was that code........the dealer did the above mentioned.......I always felt 1-2 to be a little sloppy.....not enough to complain about.........that service did nothing for my car.......still, in my opinion a little sloopy 1-2!!!!!!!!


CAN ANYONE BE MORE SPECIFIC ON THE LINE PRESSURE ISSUE......I THINK THAT IS THE XAUSE OF THE SLOPPINESS IN MINE!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!1

there are no bulletins for 1-2 shift issues for the 4t45e.

there are also no issues we've ever seen with a slow 1-2 shift.

however there is an updated pressure control solenoid and valve body plate.
which could cure this issue.

Well lfor those of you who remember, my car was going on the tranny machine for a fun run. The car ran fine, go figure. Hooking a Tech 2 up to it said something different, so I was told. Apparently I had too much air and not enough fuel. They suggested re-installing my factory Ram Air. I did when I got home from work tonight. Well, the shifting is back to being reasonably responsive, but the RPMs still jump. So I guess they said if that wasn't the prob to bring it back and they'd start checking the tranny out. Thank god for extended warranties. I'l let you guys know if anything different turns up.

Correct me if I'm wrong, but isn't the air flow sensor supposed to accomadate for the "extra" air being taken in from a cone filter or intake? I thought so, just asking other people's opinions/knowledge.

had my shift solenoid fixed under warranty. Car shifted real hard at times, and at other times seems like it took10 mins to shift. They fixed and no probs since. That was like 1.5 years ago.

Really...so did your car shift hard at cold temps and lag at higher temps? That's about thew jist of mine. Like I said, my warranty's extended until 75,000 miles so if it doesn't firm up hopefully a new tranny for me. Anyone know if it takes time for the comp to get used to the stock air intake again or no?

I really dont think they are going to give you a new tranny, probably just fix what ever is wrong

Ok, ever since I got Dr. Speed stage 2 WAI, 2 things happend. My tranny shifts firmer, which isn't a bad thing I heard.

When I go full thottle, tranny shifts fine, but when I accerate moderatly, my RPM jumps up and down and the car keeps jerking when it's trying to shift from 2-3 and 3-4. I give it more gas and it finally shifts. People with similar problems, give us an update. Thanks.

I have lower intake gasket leak too, just like you. Did you ever get it fixed?

Mine is wierd. You can tell it's been leaking for long time, but my engine oil is fine, so is my coolent in the tank. I got this car new about 2 1/2 years ago, and I have only added coolent TWICE. I have never got low coolent light, either. Maybe it stopped leaking?

Interesting. I haven't had mine fixed yet but plan to take it in next week. My coolant light came on 1 time and that was it. That was a little over 2 months ago. I haven't refilled it at all. I thought mine stopped leaking but when I took it to the dealer and asked them to check it out, they came back showing me how much it would cost to fix it. $1100. :eek:

^ I'm confused. If your car is a 2002, shouldn't it still be under warranty? If mine goes, I have until 80,000 Kms or 4 years. *crosses fingers*

I'd sell it before I dished out $1,100 on a repair.

3 year/36000 mile warranty, whichever comes first.

I have 48000 miles. So mine is over.

yep. i'm pretty sure the dealer would give me a problem with this one, even tho I have an extended warranty. If its around 500 bucks, I might get it fixed, otherwise I'll live with it until I sell the car.

Yeah, I have an extended warranty also but it's not with GM. I don't see this going to well. Just have to go and see what happens.

I didn't get it fixed then and there becuase I didn't have the warranty documents needed to get everything going. If this doesn't work out, then i'm gonna say screw it, cut my losses and prepare to sell. :(

If you do not have an indepent shop (i.e. not a dealer) you can trust, may I suggest hanging out at a few of your local parts stores and asking the couter people if they know anyone who does side work. I know about a dozen guys that will do that job for $500, assuming you didn't let it go too long (then you stand a chance of cracking the intake itself (more$$$)-and i don't know why). If you have any mechanical aptitude, a little patience, and a love of getting dirty just do it yourself. The gasket kit cost $80 (I think, it has been a while since I did one) at autozone (cheaper elsewhere, but I don't know pricing structures in your town). 5 Quarts of oil, filter, 1 gallon of dex-cool, the gasket kit, and a little patience.......you can have the job done yourself for under $120.00 for sure.

Good Luck.....If all else fails take to an independant shop. They are at least good for some savings over a dealer.

Hey guys..I was wondering if what I noticed yesterday is the same thing you guys are talking about. Now my trans has never given me problems on shifting or hunting for a gear or anything. But yesterday I floor the car from a stop and when it went to shift from 1-2 it felt as though it shifted but not completely. The RPMS dropped like normal from redline to about 4400..but then they would drop closer to 4000 and that is when if felt like the trans fully engaged at started to pull again. I just noticed it and it hasn't done it since but it was weird..it felt only half engaged or something. So I stopped and floored my car again and it kept doing it. I don't know if I just never noticed it or if it just started...is this kind what you guys are talking about. I know some people's trans have been sliipin or not going into 2..and I know what both of those are like..but is this kind of associated with that? Thanx.

I have not had to do this job, however the solenoids (I belive there are 2 solenoids in there) are accessed by removing the side cover off the trans. The side cover is on the drivers side. Do not take my word for this, however a lot of FWD gm's have their trans solenoid changed by removing the side pan (cover). It is quite cozy in there, but looks do-able with a little skill and patience.

So anyways, here was my problem. I had cracked spark plugs and really really BAD wires. I just happened to be leaving another store yesterday where my car was at and the tech ran out and caught me before I left. Half of my plugs were carbon-cracked right down the middle of the porcelin(sp). He told me that's why it misfired under load like that, but never threw a light because it was still firing somewhat. So a new set of AC plugs and wires under employee cost is 50 bucks for everything...so we'll see how that goes. Just to let everyone know, try checking out your plugs...just curious if mine were really messed up or there are others.

So did this fix the problem with your shifting from 1st to 2nd?

The more threads I read in this fourm about problems with the GA, the more I'm starting to think I should have bought a different car.

Yeah and no. It shifts instantly in all gears now, but while it's in second it likes to surge a little bit, like it'll accelerate, then pause, accelerate, then pause. My bodykit should be at my work in a couple weeks so I'm just gonna take it there then and have em do both at once.

Seth, it seems from the clip when the slippage is all done and it finally catches, it drops a few more RPMS before finally climbing again. Is that true? Mine is doing that, although mine doesn't slip for as long before it drops and catches again.

Can't believe so many people are experiencing this.

yeah when it catches the RPMS drop slightly.. i guess that's expected, picking up for lost speed ??

Yeah that could be. My kit should be in by next week so I'm taking my car back to have them do Round 2 on it. Mine isn't slipping as long as yours does, but it's annoying knowing that it is doing it.

I went to the dealer and asked one of the guys there how much would it cost to get the pressure control solenoid and the guy said about a grand. Forget that. Im just gonna wait till i have enough money and buy the tranny from domestic performance. That should fix things.

Hell you could have the whole transmission rebuilt for that. Almost.

yes i realize that i could just get mine rebuilt, but i plan on adding boost, so rebuilding it would be a waste of money.

Like a horses ass, 6 degrees plus before i put in the new DHP PCM. But I think the rest is exhaust/spark plug related.

I got more knock in gear that I do during a shift.

Well reason I asked is because since my KR is gone.. I don't notice the 1-2 slip as much. Maybe I haven't driven enough. I have to drive relatively far tonight, I'll do a little uhm.. road testing

Mine did that for whole night its shifted great. I was pumped because the problem was gone, then on my way home... guess what :rolleyes:

I sware to god that 9 out of every 10 shifts is ****ty but there is always 1 thats is perfect. its like clockwork.

Nope. Got mine fixed.
Check the line from your transmission to I guess your radiator or oil cooler? That's what the shop told me. Had to get my radiator repaired and that line replaced. I was a gallon low on tranny fluid. Shifts like a dream now.

My wife has been driving my car for about a year and we just bought her a new one. I'm noticing this problem now and I have 60,000 and I'm still under warranty.

Does anyone know of a fix for this? I'm going to try disconnecting the battery overnight to see if it fixes it.

Along with the sloppy/slow 1-2 upshift, the car also surges during a 2-1 downshift. This especially occurs when I'm pulling into my garage with some light braking. I swear I'm worried the car is going to go into the wall!

Anyone else seeing the flare or surge when it shifts down to 1st?

Does anyone have a solution to this problem? I took my car into the shop and they checked the computer and can't find anything wrong with it.

Has a flush and filter change solved this problem for anyone?

Well, the dealer checked the computer and put it on a machine to check the shift points and found absolutely nothing wrong. But, I can still feel and hear that it isn't shifting properly.

Does anyone know if this will expand into a bigger problem in the future resulting in a transmission rebuild or will it always just be an annoyance?

I can deal with it if it doesn't get any worse or cause a transmission failure. If not, I want to get it fixed under warranty.

Any ideas?

maybe take your car to a real transmission shop for an inspection and estimate, then throw it in the dealer's face
