1. Valve Body
a. In preparation for installation slide the manual valve to the far
right. You should be able to see the groove at the end of the valve
protruding from the right side of the valve body (Figure 1).
NOTE: A paper clip can hold the valve in place. Ensure that the
manual shift linkage in the transmission is in Manual position. Install
two new O-rings into the case (Figure 3). Verify valve body gaskets
are not damaged and that the case mating surface is flat. Install the
valve body onto the transmission case. Install the 10 valve body to
case bolts and torque to 71 in-lb.

NOTE: The 2-3 upshift can commonly flare and the upshift into 2nd and
4th can be harsh, along with coast downshifts while the transmission
is re-adapting. A thorough road test should solve these complaints.

Transmission Diagnostic Tips
This remanufactured valve body has been through a rigorous inspection and rebuild process, then a comprehensive, functional
hydraulic and electronic test to ensure it meets OE performance and quality. It is designed to eliminate many pressure-, shift- and
converter-related complaints, but will not correct complaints that stem from other areas of the transmission.
The following are common areas of failure or root causes for symptoms that could be attributed to valve body issues that should also
be examined or addressed during your transmission build. A clutch and brake application chart (Figure 2) is below for additional aid
in diagnosing problems, as well as air test locations to verify clutch and brake circuit integrity (Figure 3).
• Slips in 3rd, 4th and 5th or has High and Reverse input clutch failure. This condition can be caused by a cracked high clutch
piston on early applications.
• No Reverse and slips in Forward. This condition can be caused when the band anchor is removed from the transmission case,
by mistake to fill the transmission. This allows the band to fall out of its anchor. This can also be caused by a mis-positioned
valve body-to-case O-ring.
