Rich,
Thanks ! Guess I will not be able to
use the trans in my Chevelle if something were to happen to my truck.

Thanks, I'm no trans expert but I have a lot of
info. from work. Your trans is a 4L60E. It's a great trans that was to be used
only in the Sierra. At least that's what it was designed for at
first. The pan is square and it should have 16 pan bolts
holding it in place. The torque rating is 350 lb/ft. The gear ratio is 1st-
3.05, 2nd- 1.62, 3rd- 1.0 and OD- .69.

Rich,
You have helped me identify my
"mystery" trans in the past (turbo 400 with the "CT" code).
So, when you talk about transmissions, I listen. Hopefully others will
as well. Now that I've "buttered" you up, could you help me identify
the trans in my truck. I have looked in the owners manual, and the
original sales brochures, to no avail. The truck is a 2002 GMC
Sonoma Crew Cab - the little truck w/4 full doors and 4WD. I was
guessing 4L60E, but not sure. Is there a way to use the pan to
identify, like the earlier turbo 350 vs. turbo 400's ? And, what would
the torque rating be ?
Thanks,
Kent

Tom, I don't know where you got your
information. All the 700R4 is a 350? And all we did was put a valve body
on it to make it shift 4 times. Do you really think this? The 700R4 is a
fresh designed tranny. It's not even close. Even the case is different in
length. I guess if it was that simple we could buy a valve body and make a
4 speed from a 350.? Believe what you want, listen to who you want.
But here are the facts. The 350 was a medium duty trans built from 1969 to
1989. It was used in 6 cylinder and small V8's. It could handle 425 pounds
of torque. The 375B is a heavey duty 350. The 700R4 was put behind 455
engines among others. Doesn't sound like a 350 to me. The 700 in 1992
became the 4L60. Later the E was added to mean electronic shifting. For
those who are wondering...
The 4 is 4 speed, L is longitude, (rear
wheel) and 60 is a rating for strength. The higher the rating the stronger
the trans.
The 3L80 is a renamed 400. The 3L80HD is a
475.
The 4L80 is a 400 trans with OD, and the
4L80E is electronic.
The 200-4R and the 700-R4 have overdrive
planetary gears and use a lock up converter. The 200R4 and the 700-4R are
very close in torque rate. The 200R4 has a deeper OD and deeper 1st, 2nd,
and 3rd gears. Anyone thinking of buying a 200R4, be sure it says METRIC
on the pan. If it doesn't, your getting a plain 200. Also, in case someone
wanted to know, a "T" in the trans designation means transaxel. (Front
wheel). After working 30 years at Hydra-matic (now it's called Power
Train) I have managed to save some data both in my head and in my library.
I have worked on or had dealings with almost every trans we made. And I
take exception that someone thinks all we did was change a valve body and
call it a 4 speed. Most of this info is from my records so I know it's
accurate.

There are quite a few 9 and 10 second Buick GN/T-type, etc that run
modified 200-4Rs and Art Carr has one for $1599 with a 12" converter
that'll handle 700hp. For heavier cars they do recommend the
700-R4 - http://www.artcarr.com/faq.html#faq8

All a 700R4/4L60 is, is a TH350 with
Overdrive. They both use all the same parts except the valve
body. The thing about the 2004R is the fact that it cannot handle
massive amounts of torque, such as what a big block or a stroker will
put out. By the time you put all that $$ into a 2004R to make it
able to handle anything, you can have a nice 700R4 built and get a nice
new driveshaft made, and it still ends up being cheaper. I can
have a severe heavy duty 700R4 built for $900 including the converter by
my tranny guy. He has people run them with 10 second big blocks
w/o any problems. I say the only thing the 2004R is good for is
being put behind a stock built 305, that and a boat anchor
:-).
