Light duty automatic transmission primary for General Motors vehicles. The TH700R4 was a mechanical four speed transmission... it later became the 4L60, then, once electronic controls were added, became the 4L60E. Was used in GM cars and trucks up to 1/2 from the 1988 - 1992 model years.

The throttle valve in a 700r4 is what controls the hydraulic pressure in your transmission if it is not hooked up or adjusted properly it will burn up your transmission
Typicaly, If it is an over-drive it will be a TH700-R4. if it is a 3 speed auto then a TH350.
5.0L 305 cid V8/TH700 R4 tranny
Best choice would be a TH700-R4
It should be a TH700-R4
A 400 Turbo, 350 Turbo, and a 700-R4 (TH400, TH350, TH700) I recommend a 700-R4, all around best transmission, and lots better mps's compared to the others
If you have an automatic you probably have a 450-43le transmission. If your tranny goes it it usually cheaper to replace it with a GM TH700-r4 There are adapter kits available. If you have a manual there are three choices in Isuzus MBP, MSB and MXA. You need to call a dealer with your VIN to be 100% sure.
You have one of these two Suburban - 1/2 ton 1987-1992 TH700-R4/4L60 Suburban - 3/4 ton 1987-1990 TH400/3L80 Wish to confirm see link below. Hope This Helps. Check your steering coloumn. If it is factory and does NOT have the overdrive(the D outlined) then you probably have the TH400. You can also tell by the shape of the transmission pan and sometimes the pan has either a code or the actual "TH400" or "TH700-R4" stamped on it. Get underneath with a cameraphone and take a pic and go to the auto parts store or dealership.
