Hey. I have an 02 5r55w 2wd that I'm on the fence about right now and not sure if I should try and fix myself or pay $990 for a used one with unknown miles and 90 day warranty..

I bought it with 160-164k with no 2nd gear, OD flashing. Took it apart, replaced some bands, planetary, servo piston(end broke off-think OD.

After that, everything ran fine. NOw at 195k it's doing the I believe 2-3 high flare, rpm's go up to I think about 4k before shifting, sometimes more.

It has no accelaration on the low end gears, sounds like a dang 18 wheeler in it's low gears taking off, then I believe when int band kicks in, it picks up some torq and speed and shifts fine after 2-3 (not always does it-mostly when having to dump on the gas a bit).

Had issues with it jumping forward while on the brake. I've been in an 03 explorer with a good trans and could tell right away mine is pretty weak...

I was looking at the servo bore sleeve piston fix for $200. Maybe that and a shift kit, would that fix the issues I'm having right now? I haven't had any OD flashing or any check engine light codes. Haven't hooked it up to check codes, not sure if it logs if it doesn't flash check engine first.

I'm starting a business and will be pulling a 4x8 and need to get this one replaced or figured out.

 

Could it also be a torque converter problem? Does make an awful clicking type sound as well. Seems that I don't remember it being so sluggish tho. Now, if you floor it, it won't spin tires, it'll grab and vroooooom lol Prob orig torque in it as well.
