1987 auto tranny and 1992 auto tranny the same?

[90blzr]

Buddy has a 1992 suburban 4x4 with bad 700R4/4L60 in it (non electric). Would a 700R4 from a 1987 blazer be the same/work? /forums/images/graemlins/dunno.gif

thought the OD needed input from the ECU?

I thought the full electronic 4L60E transmissions came out in 94. Before that, all 700R4 and 4L60 transmissions are basically the same.

nope it needs nothing to shift to overdrive. the tranny will need a signal from the ecu for converter lockup, but 87 and 92 are EXACTLY the same for wiring, and just about everything else

the 4l60E came out in 93.

Yeap i before i swapped in a built TH350 into mine i had my 700R4 unhooked from the ecu b/c the lock up was going crazy.
