I have 1997 K1500 4x4 5.7L extended cab, that needs a transmission. Anybody know if the 4L60E in a 1997 Tahoe or Suburban is exactly the same as 97 K1500? I have swapped LS based 4L60Es and NP246 T-cases between LS tahoes and trucks with no issues but I'm headed to the junkyard tomorrow and might have to take a gamble on grabbing one out of a tahoe or suburban. I believe 96 97 and 98 model 4L60Es will work for 97 application. It's a single piece case, bell housing not removable. If anybody in Southeast VA northeast NC area I have 5.3 blocks, heads, intakes and more. Thanks and Peace!
