Hi all, was wondering about the durability of my truck, I've been doing some plowing and pulling stuck trucks out with it and wanted to make sure I'm not doing anything to hurt it. I have a 91' 3/4 ton 8600lb GVW, 350/4L80E, Western Pro-Plow. The truck as 179K on the motor, tranny was completely rebuilt about 40K ago. The motor has been run on amsoil since around 50K, continues to run very strong, had a valce job 30K ago also. Should I have anything to worry about? So far its been great truck since I got it. Just looking out for what to do to preserve it and keep it running like a top. Thanks guys.

Not to be a nit picker, but i dont beleive the 4l80E came out intil 1993, before it was the 4l80, same with the 700r-4(4l60)

When pulling on a stuck vehicle it is always best to use a snatch strap, it absorbs some of the shock before it eats the drivetrain. We always use them, and all my buddies offroad rigas have a strap, it really makes pulling easier for the truck.

Thats strange, I have all the receipts for the big ticket items on the truck like the tranny rebuild. It says 4l80E on the receipt as it was completely rebuilt. Cost was something like $1500

Well I've always been told that, and it seems to have been true. My service manual makes mention of it, so if it didnt come out until '93 it wouldnt be in a 91 or 92 manual, my mistake, maybe it was available earlier. I know that my 1991 has the non-electronically controlled model though.
