Operation CHARM: Car repair manuals for everyone.

Intermediate Range

In this range, the forward and intermediate band are applied. The transmission is in Intermediate range-second gear.

A 3-2 downshift can be obtained by moving the selector lever from Drive range to Intermediate range.

With selector lever in Intermediate range, RND oil will exhaust at the manual valve, and intermediate oil from the manual valve is directed between the reverse and T.V. boost valves.

Intermediate oil acting on the reverse boost valve along with the pressure regulator spring force boosts line pressure to 120 psi which is required to hold the intermediate band and forward clutch on.

Because RND oil is exhausted, the transmission will shift to 2nd gear, regardless of vehicle speed. With transmission in 2nd gear, Intermediate range, it will not upshift to 3rd gear regardless of vehicle speed. (RND oil is the feed for direct clutch oil in 3rd gear).
