and if it will, how long would it take to put in? does the trans need to come out? or can i get it all from the pan?
thanks for help!

1. No you dont have a HD trans, prolly more like 3.05's gears, maybe 3.29's. Those newer trannys got alot of different combo's.

2. Why do you need that kits?? That looks like its just a complete seal kit with no internal parts.

3. Yes the tranmission needs to come out of the car and would need to be taken all apart to redo every seal inside.

4. I would not recommend you do this if you dont have any transmisson repair work experience.

5. What makes you think you need to do this?

1-2 shudder, hard lag from P to D, just an overall loose feeling in my trans. 155k

"loose" feeling?

"lag"?

Sounds like a stock PCM, a transmission that needs a pan drop and filter change with possibly the addition of a shift kit...and a line pressure adjustment in the file...and new motor/transmission mounts.

There, I win.

Probably need to clean the MAF sensor and your Throttle Body as well.

Replacing seals wont help any of that.

great post! thanks, i was wondering about motor mounts ( how will i know if their bad?) shift kit has been ordered... and i didnt notice that kit only came with seals. how do i clean MAF sensor? and adjust line pressure? more or less? im an ase trainee.. so i know my fair share. buut no details. thanks!

A worn input piston seal area is common to our transmissions and can contribute to what you are talking about. Worn valve body parts/bores etc also contribute, as do wearing clutches taking longer to engage than say fresh, properly clearanced clutches.

Without some specific tools for the 4T65E and some experience, you don't want to rebuild a 4T65. It's not all that bad, it's very time consuming.

ride it till it blows, then get a used tranny. cheaper.

At the very least you want an input/3rd carrier ring resizer and a clutch compressing tool. The rest I was able to work through. Not easily in some areas. But you can get by with just those.

I paid $40 for the teflon ring resizer I think.
