700 r4 also known as L60 transmission...
change your transmission fluid and transmission filter if the problem persists then your transmission is most likely no good.
The 1990 GMC Vandura 3500 typically uses the GM 4L80-E automatic transmission. This heavy-duty transmission is known for its durability and is often paired with the larger V8 engines found in the Vandura line. It features a four-speed design with overdrive, providing better fuel efficiency and performance compared to older transmissions.
It should be on top of the rear differential.
If memory serves me right, you should have the TH700R4.
To remove the transmission from a 1992 GMC Vandura, first ensure the vehicle is securely lifted and supported. Disconnect the battery, then remove the driveshaft, exhaust, and any components obstructing access to the transmission. Unbolt the transmission from the engine and the crossmember, disconnect the shift linkage, and then carefully slide the transmission out of the bell housing. It may be helpful to use a transmission jack for support during this process.
Answer to: Where to find the fuel filter for a 1994 GMC Vandura 2500? Try looking on the under carriage just below the driver's door. There you should find a 3" cannister on the fuel line.

It does not take freon. The 1995 GMC Vandura uses the new R134a.
I have a '94 Vandura and the capcity is 3.0 lbs R134a refrigerant.
