tranny slip?
hey guys, im going to be putting a tranny cooler on the car and was wondering at around what HP will it start to slip? im going na-t and wondering if the tranny will need to be shimmed or not.
i have a question about my trans...i am Na-t untuned (at boost) but i really have to punch it to get boost anyways, and my tranny cant make up its mind...it shifts from 1-2 hard (sometimes...mostly when its colder, but it does it less if im on it the throttle just a bit...but if im just slowly accelerating, it jerks pretty bad) but really smooth every other gear. also it takes a good 5-10 seconds to shift into high gear when im cruising..so ill be at like 3.5k at 40-50 mph and it takes a good 5-10 seconds to drop to around 2k but if i put it in 4 and then back to D it shifts as soon as i do that. (keep in mind im not boosting, and i do have a tranny cooler) it was doing this a little before i went NA-t but seems worse now...also..it seems alot better when ive reset my ecu, and my check engine light is off...im still waiting on some info before i wire my o2 sim in...
I'm suspicious about the tranny too. Once I installed my SRT intake+ ECU..the car doesn't even want to accelerate. It used to pull me to the back of my seat when I punch the acceleration pedal(before SRT)...now, it's revs high but doesn't pull (with SRT). There were huge delay prior to it going (albeit very slow after it go).
Might be something to do with a transmission controller.
