Hello, sorry for my english
my car is a pontiac firebird 94 v6 automatic

I wonder if you can identify this problem:

When i drive with my car and i arrive to a stop, the car drive very slowly and when i go again, a vibe arrives and goes to the rear axle, as the sprocket-wheel don't hook.

The ABS system lighted up.

I don't know if this problem is from the automitical transmission or the rear axle, differencials ?

The oil in transmission seems to have a good quantity and for the rear axle, i bought the oil in USA with additif GM.
Besides, the oil is the 95 140 but in the GM book, it's 80 95. Is there any problem ? But i will change it.

This problem is there after i drive for 30 minutes but it's doesn't do that.

I identify it with another solution, when i put on return and put quickly on drive.

All the more so since, the car drive normaly most of the time. If i arrive to a stop and i stop, the problem doesn't appear.

I count on you because in France, we are not very good for resolving this problem.

Before i destroy my car with my tools, i would prefer to have your help…

My english is limited. If you have some documents in order to resolve my problem (pictures, links,…), there are the welcome.

Thank you to everybody.

so, you're saying it vibrates when you're in a certain RPM range ?
if so, it might be your torque converter. (the first thing i'd check, anyhow)
just have a shop put in a known good torque converter and see if the vibrations persist

If your ABS light is coming on I would start by checking out the rear brakes and make sure there is not some kind of problem with them. Have you had any work done on the car recently? If so, what? Cheers !!!

yes for slow RPM range. if the motor is slow and car runs , or not , i can have this problem. I hear the pinions well turn and when I start again "grugrugurrugru "as if it did not fall opposite. the car has like a tremble if you celere with the foot known the brake,but it doesn't move, then "clac" "light abs on"it's news this
.I remove my foot of the acelerator. 1 second and everything is good.
The other day, slowly, when i passed on a bump i got the same problem

It's possible that it's the torque converter. Does it locked the pinions well ? Can we test it on a garage with an electronical machine?

In order to answer to the question of breaks, i never took a look to the breaks at the bottom. What can provoke this problem?

The ABS central could have a relation with that.

I thank you very much for your answers.

in france We don't have big supermarket for american cars' parts ship and i complain that.
go usa

To me it sounds like a problem with the differential. Not having ABS is one clue, noise that changes with speed and running over bumps is another.

J'ai étudié français pour cinq années, mais je ne parle pas très bien.
