alot of people are different, but the way i have always done it, with your tranny full, put the full quart in. i have never done it on the grand am, but i have on an older cav v6,

is it even wise to put that in or just a normal fuild change because on the web alot of people say its crap and you shouldn't use it. i just want to try to extend my tranny life since my car has 167000 miles on it and i don;t even know if it was ever replaced, plus it kind of slips but i'm sure my clutch is worn i just don't know what to do.

i just did it to mine, im at 126k and i did the 6 qt +1 qt lucas, it shifts like a new car now, before it lagged a bit between 1st and 2nd gears

You may also want to clean the iat sensor in the intake to help with a slow 1-2 shift.

well i did it so i hope it works good. i only drove it like five miles but it seems like it shifts better. it feels like it grabs better in the lower gears

Lucas additives :thumbsdow :nono:

You just thicken the viscosity of your ATF & focked up your additive pack in your ATF.


People,
DON'T put (aftermarket) additives in your motor oil or ATF !!!


You should of just done a pan drop/change filter & gasket of the ATF & re-filled with GM DEXRON«-VI spec ATF.

I was given a free bottle during a promotion when I was doing my oil change, so at the next oil change I used it..instructions were only to use a little bit with new oil at the time of oil change for low mileage engines which mine was. It was something like 1/5 lucas and 4/5 oil..or something like that, I cant recall at the moment.

Next oil change, I had to have the engine flushed becuase the oil had gunked up inside and formed almost like a sludge..allbeit it was after 5k oil change.

I believe the same lucas treatment can be used for the tranny, (same bottle)..if that is the case I wouldnt use it for mine. I did a simple pan drop and filter change at 110k and it still shifts like the day i picked up the GA at 46k. I am at 135k now.

It's right after the airbox. The connector looks like this. Minus the red wire.

Just twist and pull and it will come out. I used some electrical contact cleaner spray. Then i just gave it a good bath. Also put a little Vaseline, chapstick or something of lube on the threads so it can go back in with ease.............

I found out about this when i put a little too much oil on my K&n

I'm with Mike on this. Most additives are junk and do more harm than good. You're best off just sticking with good quality fluids. If you want the best, get the dexron VI ATF.

Instead of making a new thread, I'll just ask my question here.

My GA just rolled over 60k miles, and I'm wondering if I should get some kind of transmission service done soon. I've had the car since about 50k, and so far I've sea-foamed it, and put new spark plugs and a fuel filter in. I've also changed the oil every time the "oil change" light comes on (three times I believe?).

What should I do as far as transmission service goes? I'm know that a previous owner of the car had it leased, but I'm unsure if I'm the 2nd or 3rd owner, so I'm not clear on its service history. So should I get a flush or just a fluid change?

Thanks,
Amir

I think I need to do a drop/filter change. I'm at 47k and my 1-2 shift is getting worse every month ;crap

well i done a fluid and filter change in my ga the day after i posted in this thread. and so far i have had absolutly no problems. and i also have abou 20k miles on the cavalier since i put it in it, and iv had no problems, some people have great luck, some have awful, just like some people have extremly bad luck with just regular fluid and filter changes, no additives and yet there trans still ends up getting worse right after the change. noone can tell you rether its going to hurt or help your trans, if youv got the guts try it, if not then dont i guess.

FACT:

GM's DEXRON«-VI ATF will specify a maximum viscosity of 6.4 cSt at 100║ C.

From: Lucas Transmission Fix - Production Spec. Sheet (http://www.lucasoil.com/images/medialibrary/trans_fix.pdf): Viscosity @ 100║C cSt = 48.0


Enough said...:banghead

well when i put the lucas stuff in i only put half the bottle in and for right now it works great, but yes the viscosity of the lucas is 48 but you also have to look that you are mixing that into about 6 quarts or however much the tranny holds, so in the end you are only increases the vicosity of the tranny fuild already in their. which it most likely will have a lower vicosity because its not brand new trannsmission fuild. so to me it is only renewing the viscosity of the tranny fuild without replaceing the fuild. which to some may not be a great idea but to others may be an ok choice since for me i have 168000 miles on my car.

If you change your transmission fluid every 50k miles I dont think you will have problems with your transmission unless you beat the **** out of your car. The owners manual says every 50k, I've followed the maintenance schedule down to the "T" since day one when I bought my car brand new, a year after I graduated high school. I now have 116k miles on my car.
