Tranny was replaced, there isn't any oil leak(s). However, problems persist when I put on the pulley. Probably too much heat and/or pressure. That boost is/was unbelievable....

 

I have these mods plus tcu mod. All tunes were real time dyno tunes. Mods were done at appx 39k miles. Trans fluid was flushed about 43k miles. Car is a scream...No known issues.

 

I don't think the pulley and tune would affect the tranny like that, for one thing they're pretty tough. There is a lesson here! You can't just throw parts at the car, it should be done systematically, with some sense of where you are going with it. Pulley and tune are usually done in conjunction with a DCAI and larger heat exchanger and manifold mods. Each change affects everything else so search the forum, all the info you need to do a good job is here.

 

I have a 155k srt-6 with pulley, pulley saver kit, cai, the needswings cooling package and NO TUNE. My car is fine and has been since I put all this stuff on. I bought it with 120k on it for next to nothing. I'll get it tune one day. I know im leaving power on the ground.

I'll say this though, if I dont let the car warm up the tranny shifts hard on the 1 - 2 when cold. It goes away when it is warmed up though. Given the age and the mileage I just chalked it up as an old age high mileage thing. Doesn't bother me though.
