Joel: You wouldn't happen to have this info on the 4L80e would you? BTW, you file above helped me out tremendously today. Was doing a shift kit and had all the valve body bolts in a handy dandy bolt sorting box (has holes arranged the same as the valve body so I don't have to remember where the bolts go) but as can be expected, turned it over and dumped them all out. Since there are seven different sizes (lengths and head sizes combined) I was at a standstill until I remembered your post. Thanks for the help!Originally Posted by Joel_SS

Hello all, newbie here. I read a few posts & you seem like a great group... so I joined.
QUESTION 1: I have a 1997 Express/4.3/4L60E shallow-pan while the 2000 Astro/4.3/4L60E Deep-Pan. Will the Express trans work in the Astro without major mods? Both trans are One-Piece housings.
Tomorrow I'll have to measure the total length, (it's to dark & cold now).
QUESTION 2: To rebuild the Astro Deep-Pan, is there any quirks I need to look out for verses a normal automatic? My last rebuild was a (late 1970's) Turbomatic 350.
HISTORY:
This Astro (mileage 200K) trans shifts fine in 1-2 but has no 3-4 gear so I'm assuming the clutches R-Gone. Fluid is only "ever-so-slighty" burnt & clear-brown. I haven't dropped the pan yet for inspection, (just got the car today).
Direct answer would be REALY GREAT, my free time is very short.

Hi fm-usa,
Welcome to the forum...
I couldn't answer your questions with certainty...
but here's the transmission wire diagrams for the two vans, the wires/pins appear to be the same, so my guess is they are interchangeable.
Yes, 4L60E suffering no 3rd or 4th typically is 3/4 clutch failure.
With the deep pan you have to get the correct filter.
(if others have more info please respond)
BY-THE-WAY... is there a GOOD website dedicated to just Astrovans? So far all I found is body-rebuilders.

When times were good I had my '97 Express Pro-rebuilt, todays economics is just killing me.
THANKS!!!

Good info!
Here's a little more that might or might not help some others with problems: Circuit 1020 in S-Series (Blazer, Jimmy, Bravada, S-10, Sonoma) controls tranny functions, and is subject to failure because of a switch in the steering column connector harness. Many transmissions have been rebuilt because of this failed $80 switch.
Failure of this circuit can make the tranny default to limp mode, 3rd gear only, and can trip the tranny fluid pressure controller to max, which will make the tranny detonate in a week if not fixed, or at least re-set in the computer for temporary fix.
