Used truck info

[DaveBr]

I'm looking at buying a 98 GMC 1/2 ton ext 4x4. It is out of town so I'm not able to get a visual on it yet. Pics are coming monday. They sent me a copy of the build sheet and the tranny code is MT-1 TRA 4-SP ELECTRONIC AU. My question is can anyone out there tell me if this is a
4L60E or 4L80E tranny. Thanks.

Mt1 : Transmission, 4 Spd, Auto W/elect Controls H.d. (hydra-matic 4l80-e)

[6.5 Detroit Diesel]

Ok, so we got guys from Manitoba, Alberta, and BC posted on this thread.

With the tranny, I don't believe the 6.5 ever came backed with a 4l60-e. It was either the 4l80-e or the NV4500 5 speed.

That's one of the things I love about my Tahoe, It is a 1/2 ton truck with a 3/4-1 ton transmission.
My 85 Blazer (I miss that truck) with the 700R4, I had the trans rebuilt about 4 times, althought I may have pushed its limits.

Thanks for the info I feel much safer with the 4L80E.
Cheers

O.K. Going to look at this truck on Sat. They sent me pics and it looks good. According to VIN this rig has an S code engine. I Know there is also an F code engine. My question - is the F code available in a 98 1/2 ton truck or is this S code the less HP version of the 6.5?
