Default Has anyone beefed up an auto tranny?

Basically: Has anyone beefed up an auto tranny? My tranny I feel is going to go, like after driving a bit it feels like its not running right only when its cold. I dnt wana have my car out again for a weeks to swap to a 5 speed so Im willing to spend so I can keep my auto going for longer.

You should contact them.....they can give you more information. The build involves an upgraded torque converter, valve body, clutch packs, etc. I'm sure if you give them a target power they'll be able to build for it...

Wait what is the main issue? Does it lag its shifts when the car is cold? Or does it also do it when its been driven for a while? Unless your boosted in some way the tranny will hold fine. If its only laggy when cold thats because its trying to keep the RPM's up to help the car and transmission fluid warm up faster.

no its fine when its cold but when it gets warm it doesnt do well like i dnt give it more then quarter throttle becuase the rpms dnt go any higher then 4 and then it like idles up n down when im driving....

i agree with the last sentence that tc4eva posted, also try putting a tranny cooler on the car if you like to beat up on the car every now and then and it will also help the tranny last abit longer because you won't heat it up too much.

Ok well if your tranny was going out it would shoot the RPM's up, but the car wouldnt move because it was slipping, or it would just really lag when trying to shift into the next gear. I wanna say you might have a different problem, but I could be wrong. When was the last time you changed the A/T fluid? And I would also recommend a tranny cooler for your car. I still need to get one myself. Im gonna assume that your somehow boosted since your in the F/I section. Is your tune spot on?

I have 32k on my car I was just looking at changing my tranny fluid. I have a tranny cooler.... that never made it into my car we forgot and then just said get it later but I dont rlly beat on my car I just dnt like the fact when I give it any gas it like rejects it almost. The next thing was a professional tune but I think I'm going to get different injectors because my RCs idle weird. It just has a base map on it now

Heat is the #1 kiler of automatic transmissions..you should have put on the trans cooler on a lot earlier than this.

If you dont have a tune, it will cause weird problems. A basemap is not a tune. Its made just so the car will run long enough to get it to the tuner. They are usually setup very very conservatively so that may also be causing you problems. And try changing the fluid as well. What size RC's do you have? Anything more than 440's will cause the car to idle too rich since the computer cant compensate. And I dont kno if your base map was setup for the RC's that you have currently.

Im running 440s and I was just trying to pick a tuner for the emanage ult. I want to go to ptuning but I would trailer the car there so I was looking for somewhere closer and I found RIPP mods in NYC.
