I allready got a Series 2 NA. As far as the tranny goes, there are some aftermarket pieces out there that can beef it up some.

Un modded the 4t60e has a much better track record then the 65e.

Personally i'm not worried about mine for the major mods i'm doing this summer.

Does your rebuilt tranny have a warranty on it Twister?

Yea. I think it is a 1 year or 3 year. I got to check the brochure they gave me about the 4t60e. You think if I do anything to the tranny as far as beefing it up, that the warranty will be voided?

Modding the engine shouldn't void, but tranny maybe. As long as you don't burnout all the time or do bad things tot it, it should last.

ok, see if I got this straight:

95-99 NA got the 4t-60
95-99 SC got the 4t-60 HD

2000+ got the 4t-65

Why not the 4t-65HD for the SC version? Is the 65 already beefier, and didn't need a HD version?

(Side question: What exactly is the difference from the 60 and 60HD?)

92-99 NA 4T60
95-96 SC 4T60 HD
96+ SC 4T65 HD

I think.

HD gets an extra spider gear in the diff.

that'* prolly the least of it... when i first started workin around the 4L60/65, the only differences I saw were in the planetary sets and the pan... after a little bit of time and a lot of learning and paying attention, it'* kind of mind boggling the differences (again, this is the L60, but i'm sure the whole setup is very similar to the T60) - once you get down to it, you're looking sometimes at different clutch material, different output shafts (the turbine shafts are usually the same), shot peened output shafts, different valve body assemblies (usually only one valve different between reg/hd), slightly different pump, different spacer plates, etc. there'* a TON of variation...

not nockin what you said, just addin info

Can't compare FWD and RWD trannies. Our yukon has 330lb/ft from a 350 into a 4L Bit more then a 3800....

All trannies were 65'* 97+ guys!!
