NOTE: Plate included in this kit will fit *all Turbo-Hydro “350” non -lockup transmissions even though it may

not look the same as the plate presently in your transmission. Spacer Gaskets included in this kit
must be used. Note will not fit Turbo “250”.

STEP #1:

Transmission should be cool before installing. Also, place gear shift selector in neutral. If
vehicle is on the ground, secure so it will not roll.

STEP #2:

Remove drain plug in pan and drain oil. Olds., Buick and Pontiac do not have drain plug, and
therefore, must be drained by dropping transmission pan. Recommend leaving a couple of
bolts attached until most of the oil has drained.

STEP #3:

Remove transmission oil filter by removing two screws. Be careful not to lose gasket.

STEP #4:

Remove kickdown valve wire by pulling pin out of kickdown lever in valve body (Fig. #1).

STEP #5:

Before removing valve body, note position of the gear shift linkage hooked to the valve body
(Fig. #2). Remove 17 bolts from valve body. CAREFULLY lower valve body and at the same
time slide angled shift pin lever from gear shift selector. DO NOT drop valve body or manual
valve with angled shift pin.

STEP #6:

Holding spacer plate with your hand, remove spacer support plate bolts.

CAREFULLY

lower

plate as there are four small teflon balls sitting on plate. Also, watch that the governor screen
and oil pump screen do not fall out. These screens are located in case underneath the valve
body spacer plate. See Fig. #3 & #4. Olds., Buick and Pontiac have two governor screens in
rear of case, one in each passage. Chevy has only one governor screen.

STEP #7:

Sometimes the front servo will fall out when lowering the spacer plate in STEP #6. If so, be
sure to reinstall per Fig. #5.
