If I remember correctly the "wt" or more accurately the "W/T" stood for "Work Truck" and was available in the Cheyenne package with the single cab, "fleet side" long-bed with painted bumpers and outside mirrors as well as a different (silver painted) grill to start with around 1988/89. I'm not sure of the engine transmission combination but every one I remember seeing in the late 80's and early 90's was the 5.7 liter V8 with throttle body injection and the 700-R4 automatic transmission. Around 1990 GM made the 3500 series available with the 454 (7.4 liter). These models were an affordable alternative for new truck buyers who needed a long bed truck for business usage. These trucks came with air-conditioning and AM/FM radios but had vinyl bench seating as well as manually adjustable outside mirrors, and manual (crank) side windows.
That would be the 4L60E
Work Truck
That means work truck. It is the most basic truck package, even a deduction in the NADA book. Normally rubber floors, vinyl seat, maneul tranny.
Late 1996 to 1998 year 4L60E Transmissions will work with no problems.
4L60E in 1/2 ton Trucks. 4L80E in 3/4 ton Trucks.
Half ton.
Remove the retaining ring from the top of your 1997 Chevrolet 1500 ignition cylinder. Slide the ignition cylinder out and remove the wiring harness.
