Thread: Question about hard shifts, trans mounts and additives

So I got a pan drop, filter and intense shift kit installed, which was great, and shift much better and firmer, now with the addition of my overkill pcm, its pretty ridiculous.. the 1-2 shift at WOT makes it shift so hard it sounds like its clunking, 2-3 is a little better but not much.. Nothing seems like its wrong, but the trans feels like its shifting to hard for the motor, in a sense.. So Im gonna check the trans mount today, ( even tho when it had the shift kit put in a few weeks ago, he said it looked good and there is no leaks ) .. But Are there good solid mount ( trans or motor ) that wont vibrate the piss out of the car inside? Just ttrying to 'tighten up' I guess you could say , what feels like is alot of movement under the hood..


And are there any good additives to put in the fluid? Amsoil, Lucas etc


And on that topic of additives, Has anyone ever used Redline Water Wetter? If so Im guessing its ok for use with all coolants?

Did will know you had a shift kit?

The line pressure is likely too high.

Just use a quality synthetic transmission fluid.

Will did know I had a kit when they dropped the pan for dex6 and a filter.

Also when it shifts at higher rpms 5500+ I feel a slight vibration. Not sure what that is either but it feels like it comes from the rear. Like the suspension possibly? Cuz it does sag pretty good in the rest when I get on it

I think I told will it was a trans go. Not sure if he would adjust for the 2 different kits, but this is way harder shifts than my SSei , which I know for a fact was trans go. I'll have to find my receipt

Your input shaft didn't I'll bet.
