great! soften the shifts or what? and welcome back.

Yeah...lets see how it shifts and go from there...I may want to make some pressure changes as well.

do i need the pin? if i get the sonnax 4th gear and the orgean trans 1-2 servos?

[GasGuzzler]

No pin for anyone and the Vette stuff is only 2nd. All the old pistons I've removed had the same numbers on them and my Denali from 2003 has an M30. I've never been in it but it would not surprise me if it had 5-pinion planets. To answer the question, yes...an 08 or 07 or...can have a 4L60E no matter what anyone here says no matter the year or engine size or vehicle weight IF you call all M30's 60's, all M32's 65's, and all whatevers 70's. The fact remains there is hardly a difference in strength between a 60 and 70...there are more differences by year and what are common failures. Buy the Vette kit from OPT off eBay (cheaper) and get a billet 4th piston somewhere if you want that.

Your 03 Denali definitely has 5 gear planetary set. My C3 has it and I believe it has the M30 code as well. In 2001 they called it a 4L60eHD.

Go Nathan!!!!!

[PlaneJaneSS]

So this sonnax servo is better then the vette servos??

[1slo4.8]

so they claim but if im understandin nathan you can't tell the difference between the two.

I hope I don't have to see inside of that thing...the 6.0 AWD half ton 60E is a bastard to get out compared to all others because of the goofy exhaust. Guess it could use new T/C fluid though at nearly 90K miles. It's been 2400 miles in 2010!
