Harder then when the tranny was put in for sure. Recently changed to Dex VI fluid but it was shifting hard before that anyway. Tim King built the tranny (Ive been told he is good). The shift kit is "medium" and it was a noticable difference over my stock transmission for sure... but now it almost feels "violent". I went through and custom tuned my tranny settings to my liking but it never shifted this hard until now... could anyone look at my PCM BIN? Tranny parts list:

3.69 gear set kit with bolt on reluctor wheel
7/8 chain
shift kit
ratcheting pawl sprag
input shaft
hardened 4th clutch shaft
new pistons, seals, gaskets
updated raybestos clutches
improved boost sleeve
new sensors
new filter

I really want to get a refresh with a GM 1" chain installed but I dont trust anyone local to do the work.

There was a lot of clutch material in my tranny fluid when I changed it out so I wouldnt doubt it . Yes, it shifts hard with normal driving.

Have you scanned for codes or watched PCS commanded current/amps? Most all codes set for the trans will put the trans in default-max line pressure and make very rough part throttle shifts. If PCS current is constantly around .1 amp then there is a code or a problem as it should very between .1 and 1 amp, normally around .8 with low load on it.

My PCM isnt throwing any codes that I can pick up with my Powertuner. I will scan for PCS commanded current and report back!

Good thing my work isnt far away... but my tranny temps rose steadily today and got pretty damn hot. Ugh... check out my ClubGP post and let me know what you think.
