i have 94 sub 2wd 5.7/w 4l60e a couple of salvage yards told me 2 different stories. one says i can only get a trans out of 94 truck/sub the other says 93/94 only,another says any off of 4.3 blazer/astro and up into trucks and subs. newer trucks have 2wd and 4l60e RIGHT?n how come i cant use any of these and what is the difference between the 93/94 and the newer 95 and up 4l60e? im trying to find a low mileage newer one if possible. oh what about the 700r can i use one of these? and will it make my check engine light come on if i switch to this? if it makes any difference my sub was built late in 94 could be early model 95 ?

I thought the 4L60E is a tranaxle on GM cars. My wife's '97 Bonneville has one.
'94 Burb w/350 should have the 700R4.

there are different types,gm changed from the 700r in the 93 suburban and went to a 4l60e,but a certain one only for 93 and 94 thats what im trying to find out whats the difference of them thereafter 94

4l60e is electronically controlled so i'm assuming they changed the solenoids/pcm sometime around 95
