Thanks to one of you guys.....

I'm building a 4T65E and swapping that into her this spring. The info about the TCM from a '94 3500 chevy diesel used to control one was too much to let pass.

Besides, now I can easily get posi, those locker 4T65 diffs are everywhere, and and and.....

the guys who did the swap already also did the mods for single chain from a 440T4 and most of it looks fairly easy. This will allow me to go to a grand prix shifter easily enough and I wont have to fab a micro switch shift plate either!

Honestly if i had the money I'd buy the 4T65 Raptor trans and 4k stall convertor from Performance trans, But looking at the siite, I think I can build one.....
Transmission is what makes it go right?

2450! Hell that is 300 pounds lighter than my Beretta!

I don't necessarily subscribe to the 100 pounds per tenth thinking, but maybe I should go on a diet.

And I LOVE MY 3t40!

Yeah 2nd gear blows on the 4t6*E cars. 1st is perfect I think. Rips very good, but isn't so short like a manual that you blow the tires away instantly. At least now my 2nd gear isn't so bad with the extra power my 3100 has. It still moves now at least, but it could be better.

Dyno a 4t60-e and a getrag 282 with the same motor and you'll see the manual puts down A LOT more power. Plus the auto adds 130lbs more to the front of your car.

I dynoed the same day as michael from FFP and i actually beat his HP number by like 5hp but he got me by like 8tq lol... he was kinda cracked lol made me . his was a '92 Z34 (284) mine is a '95 Z34 (4t60-e) both had Intake, Exhaust and UD pulley IIRC... same mods. But for some reason i was dynoing higher then all the other auto guys by like 10-15hp.... Must have a Wed. Motor

Yeah, there can be differences motor to motor. Stock my car blew away my friends 96 Corsica which are lighter than Berettas. He did have a MAF and was OBDII but the car ran fine, but my car has always seemed to be faster than it should be when faced against comprible vehicles.

Also the 284 is bigger than the 282 and may have heavier rotating parts that make not much difference from a 4t60-e. It would be interesting to compare the same motor (from the same car) with a 282 to 284, and 4t60 to 4t65e. Would be a lot of work to do that but would be very interesting.

284 DOES have larger parts in it that would sap some of the power coming out of the motor...

kind of like comparing a TH350 and TH400, the beefier ones is heavier and stronger, but looses more power on the way to the wheels...
