Question 4L60E question

Does anyone know if a newer model 4L60e fit our engines? I know that the tranny is electric and has all the sensors and stuff but I would change that out and convert it to a manual shift if need be. I've got a lead on a new one but it came out of a 2000? Silverado. I'm just wanting to know about the bolt pattern compared to ours.

4L60E is identical to 700R4 but elctric. 4L80E is the beefy version of the 4L60.

Right I knew that but I was wondering about the newer style blocks and their bolt pattern.

I just put together a 2002 model small block 350ci and it had the same bolt pattern for the trans that a 700r4 takes (and 4L60&80),

the 700R4/4L60/4L60E are based on the TH350, with an added OD gear.

the 4L80s are based on the TH400, with an added OD gear.

one is not a beefier version of the other, they are totally different animals.

didn't know how technical he wanted so i posted a quick spit of info. yes the new vortec motors have the same transmission bolt patterns as gen1 and gen2 blocks. hte motors themselves are quite different and won't change anything over to my knowledge

This may sound stupid and hope B doesn't mind me adding a question in here, but what makes the TH350 and TH400 "different animals"? I've rebuilt a couple TH350's but never a TH400, so this is a legit question I'm not trying to be a smarta$$. I guess I never really looked around to find out what the difference really was.

Matt, the internals of the TH400 are more heavy duty, and the parts will not interchange.

Ok, that's what I had always heard but I wasn't sure if that's all that was different. Thanks!

Also the gears are different ratios as well. http://www.geocities.com/z28esser/ratio.html

(I'm a newbie at engine/trans)how would you hook up the electrics for an automatic? Would it be a straight forward plug and play? I was thinking of going with aftermarket tilt w/ column shifter. (I have a lead on a 95 LT1 with a 4L60E)

jay-dawg, with a 4L60E, you have to run a computer (which you need for the LT1's injection setup anyways) because the trans is entirely electronic.

Brandon,
It will bolt up, but you will need a computer to control the shift points. I think I would get a 700R4 instead.

Just get a 4L60 instead of the 4L60E. Same as a TH700 but with some reliability tweaks.

actually, you can run an LT1 without a computer, and someone out there makes a kit to work a 4L60E without the injection setup. however, running an LT1 requires a carbureted intake manifold. as far as i know GM Performance Parts is the only manufacturer of such an intake. it is sold uner PN: 24502592

Quote:
This Gen II design LT1 small block intake (RPO LT1 type) will fit late model Corvette, Camaro/Firebird, and Caprice engines. With the longer runners, it can increase engine torque by 30 lb/ft. without sacrificing top end horsepower. This will allow enthusiasts to take advantage of the advancements of the Gen II engine’s design without installing a computer pre-emission controlled vehicles.

Technical Notes: The bolt pattern on this manifold flange was revised and the holes rotate 27° to match the Gen II cylinder heads. There are no water coolant holes on this manifold, and it will only fit 1991 or later Gen II engines.

Actually if I got that I would have changed it to manual shift or even grab a 700r4 case and install the good guts into a old case. Maybe this would work as well? Maybe I can get it cheap enough and swap it for a built 700r4

brandon, swaping 4L60E guts wont work in a 4L60/700R4 case. the earlier model trans is hydrualically controlled, where the newer trans the shifts are controlled electronically.
