i have a 1996 Bonnie SSEi. I've just got a few things done(view signature) but can already feel the tranny getting weak. my car was a blast when i first did the mods but now 9.30'* in the 1/8 are beginning to become boring. any suggestions on the tranny? help! :(

Are you asking for a diagnosis? Prediction? Or what a Performance Build would entail?

you have (IMO and others) the Better trans for the Series II.....unless you feel the trans slipping, you dont have a problem...how does your fluid look....dark..smell burnt???

there are alot of mods to go faster

Diagnosis.. You have a heavy foot and your trans is paying the price
Prediction... Failure eminent
Performance Build...see Willwren mod list in sig

(j/k) it sounds like you are aware it'* taking a beating and you like the power.

What trans comes on a 93 ssei? I can't find an "HD"?

i would like to add some hp to the motor, however, i believe i need to build the tranny a little or possibally replace it with something stronger. but i cant find any parts for the 4t60e. does anybody have any suggestions? i would like to ee it run mid upper 8'* in the 1/8th. i know what the motor needs it'* just the tranny that sucks. it lets go at the top of 1st and thetorque converter shudders bad when engaging, espesially when in OD, i wish i would've got a '97 :( HELP!!!

the 93 SSEi 4T60 HD

I'll move this to Performance and Brainstorming for better exposure.

ALL parts that are available for the 65 are available for the 60 and have been for along time...they ARE outhere.....you just gotta look.....any reputable trans shops will be able to getyou the parts...we just have had 2 60'* rebuilt and BEEFED UP in the past few months....SSEiMatt and Willwren

and drive it daily (well, at least every OTHER day).

Do a search of my topics. You'll be able to follow along with my trans build day by day. The 4T60 in some respects is actually a more reliable trans to start with. Failure rates with the 4T65 (in stock for stock comparisons) are 3 times the rate of the 4T60.

The most common failures in the 60 are the diff pinion shaft or it'* retaining pin, and the 2nd gear clutches, however, this is with the lower (rpm) torque curve of the Series 1 L67, and without the 96'* PCM torque managment. So it'* a game of guessing to see what your long-term failures would be.

Beef it all up. HD TC, custom Diff (beefed up) and a full-blown shift kit, with any and all options. You'll do fine with that setup.

My 93 is putting down more torque now (probably) than your 96, and it'* doing it at a lower (more dangerous) rpm, with much less torque management in the PCM. The trans is handling it (at least for the last 5 months) with flying colors. I'm very impressed with the build.
