Service & Appearance Care
If you have a 4.3L engine, you will have a flip-top handle. Flip the
handle up and then pull out the dipstick and wipe it clean with a rag or
paper towel.
2. Push it back in all the way, wait three seconds and then pull it back out
again. Flip top handle should remain in open position.

3. Check both sides of the dipstick, and read the lower level. The fluid
level must be in the COLD area for a cold check or in the HOT area or
cross-hatched area for a hot check.
4. If the fluid. level is where it should be, push the dipstick back in all the
way.
I f you have a flip-top handle, flip the handle down to lock it in place.
How To Add Fluid:
Refer to the Maintenance Schedule to determine what kind
of transmission
fluid to use. See "Recommended Fluids and Lubricants" in the Index.
If the fluid level is low, add only enough of the proper fluid to bring the level
up to the COLD area for a cold check or the HOT area for a hot check. It
doesn't take much fluid, generally less than a pint. Don't overfill. We
recommend you use only fluid labeled DEXRON@lIE, because fluids with that
label are made especially for your automatic transmission. Damage caused by
fluid other than DEXRON@IIE is not covered by your new vehicle warranty.
After adding fluid, recheck the fluid level as described under "How To
Check".
When the correct fluid level is obtained, push the dipstick back in all the
way. Flip the handle down if you have a flip-top handle.
