Automatic Tranny's: good or bad
Can anyone tell me if there have been any problems with the automatic tranny's in the C5's. Is it a 4L60E transmission or different? I know it's a different car, but I had a '91 GTA with an auto tranny and it was a worthless transmission. Any help would be appreciated. Thanks.

4L60E is right. Ay this point, I have not had any trouble with my 98 C-5 ,but I do not drag it a lot either. Hopefully, one of the members from this forum will give you a better answer. You might want to check the TSB's to see if any exist for the auto trans. Good luck.

Good transmission for stock or near stock power, wont stand up to much modding though. :cheers:
Mine hold up pretty good.
I now have an FLP Level IV upgrade, though, because I have too much hp.

Good... the late 4L60-E is great platform trans. Lots of upgrades avalible and when tuned right can live up to alot of horsepower. I personally have one in a c-5 about 550 hp. and a 4450 lbs impala about 535 hp. If it can survive an impala... it can live in a c-5 nooo problem!!! :smash: :smash:
The trans in your 91 GTA was a 4-L60 aka 700r4. a bit "clumsier" different valve body mostly. not supprised you have performance issues with it in stock trim. I would have alot more faith in the late-model a-4.
