Checking Fluid Level

WARNING: This page does not describe the selected car, but rather 28 other vehicles, including the 1987 GMC Vandura Special, 1987 GMC Vandura, 1987 GMC Value Van, 1987 GMC Suburban, and 1987 GMC Safari. However, it is still accessible from the selected car via links, so may be relevant.

NOTE: One pint of fluid will raise level from "ADD 1 PT." ("ADD") mark to "FULL" mark on dipstick in a hot transmission. DO NOT overfill.

With vehicle parked on a level surface and engine at idle, move selector lever through all positions, ending in "P". Remove dipstick, wipe clean and check fluid level. Fluid level should be between "ADD 1 PINT" ("ADD") and "FULL" marks on dipstick.

If vehicle has been operated for an extended period of time at high speed, in city traffic, or pulling a trailer, an accurate fluid level cannot be immediately determined. Transmission must cool for about 30 minutes after vehicle is parked, before fluid level is checked.
