My 96 4L60E has 102k on the clock and it slips at WOT. Need to find a rebuilder around Houston and this is what I have seen so far.

4L60/5E Street & Strip Stage I Build-up


For vehicles from stock to 450 r.w. hp. Complete tranny rebuild inculding the following Stage I Upgrades:

*Transgo 4L60E-HD2 Shift Kit (including internal modifacations)
*HP 3rd clutch piston Return Spring Kit
*13 vane pump kit, clearanced to spec.

*Alum. Accumulator Piston Kit (replaces plastic ones that tend to crack)

*Century HP 3-4 Clutch Kit: Special Alto Red Eagle Racing frictions, Koleen steels, pressure plate & snap ring. Increases clutch count from factory weak 6 to awesome capacity holding 9! A must for any HD/Performance 4L60!

The price seems a bit steep. My Z will probably never see 450 hp. What do you boys think.

 

i bought a rebuild kit for my trans. for $130 from AXIOM in Norfolk, VA. its all borg warner hi energy and trans tec stuff. the guy that built mine (he has been doing it for 25 years) said it would hold up to 700 ft.lbs. of torque......just a thought.

 

We build a better transmission for less money.

i was going to say check out cpt, but frank beat me too it. Hes got great prices and alot of people on this board have had really good luck with his trannys. This winter i plan on going with one of his rebuilds.

 

Cahall FTW!!!

 

I would love to use CPT but dropping and shipping my tranny is not feasible. Frank, do you do house calls?

 

LOL...Well, I was in Fort Worth for a week last year, but I didn't take my tools with me.....
