http://www.355nation.net/forum/i4-i5-engine-drivetrain/17003-4l60-e-mod-upgrade-info.html It has alot of good info along with rebuild kits and stuff.

 

I guess what i really want is opinions on what to use, i was thinking upgrading to the 5spurs an all so technically 4l60-4l65 conversion... going to look for a 2000-2200 stall torque converter.

I have the superior servo already, i'll upgrade the boost valve to .490

keep the old pump...

should i be looking into upgraded input/output shafts...hardened?
monster makes a sweet kit for 900 bucks, even has a chrome pan with a drain.

 

If you're 4x4, I don't think their pan will fit.

 

Any idea why? i don't see how there could be clearance issues with our pans, i'll have to double check.....

 

The 4L60e pans for the 4x4 trucks are unique to the 355 to allow for driveshaft clearance. I haven't seen any aftermarket company provide a trans pan that will fit the 4x4s yet, so that's why I'm suggesting that the pan may not fit.

 

makes sense... hmm i'll contact them; i have questions about the kit anyways...
Sucks to see a 900 $ kit not include a converter lol

 

If you rebuild it that case has to be absolutely spotless. New pump, cleaned out entire case really well. I'd upgrade the planataries right away. There a known weakness in the 4l60e. Do it right the first timer not the second time around.

 

i know its aluminum case so probably shouldnt power wash it huh? lol...

Im talking with monster right now...
deff. upgrading to the
Rear Heavy Duty 5 Pinion Planetary
Front Heavy Duty 5 Pinion Planetary
Heavy Duty "Beast" Sun Shell

 

That's what I did up grade to the 65 and add trans cooler and a external filter

 

did you go for the input and output shafts too? this kit doesnt include any hardened shafts..

hardened shaft
hardened shaft....

anyways...
what did you do for a pump? factory?

You can pressure wash :shrug: make sure its dry though. Everything needs to be cleaned.

i figured might damage aluminum...keep it low i guess

nah that wont hurt aluminum as long as you dont use anything with muriatic acid that will etch in no time. if you are using an ultrasonic parts washer just use cascade dish washing powders with hot water, it does wonders for even heavy grime. even if you just use a big plastic bin to clean it in. a good friend of mine has an ultrasonic parts washer at his house and it is awesome, cascade is all he uses in it. he is also a master at GM transmission building.

 

we never rebuilt pumps when i worked at a GM dealer, depending on what the failure is. clean them out and reinstall them.

 

well this is interesting, the horseshoe clip on the servo exploded... the face of the innermost piston is destroyed.. hmm.



now i have to figure out whether or not i can still use the case >.< ahhh

 

oh shit is that a super servo pack ?

 

it was...

i emailed them... waiting...

other damage includes Cracked pump stator, and destroyed low/rev sprag...

i dont think im going to pull apart the low/rev piston..i have no reason to believe it has any issues... i may pull the spring pack out of the input drum though..havent decided..
