Transmission Fluid Leaks Due To A Blocked Transmission Vent Pipe

MODEL: XJ-S

DATE: 6/91

ISSUE:

The transmission breather pipe can be blocked/kinked by the foam pad above the transmission. The pressure build-up causes a fluid leak at the joint of the two piece dipstick tube.

ACTION:

To check that the rubber extension hose for the transmission breather pipe is not kinked or blocked by the foam pad above the transmission, perform the following operation:

^ Raise vehicle on a lift.

^ Loosen and move both intermediate exhaust pipes to gain access to the transmission mount crossmember.

^ Support the transmission and engine assembly with a transmission jack.

^ Remove the crossmember and spring mount.

^ Lower the transmission approximately 2" to gain access to the breather pipe.

^ Position the breather pipe so that it is not blocked/kinked by the foam pad above the transmission.

^ Clean off any fluid from the dipstick tube and the transmission case. Raise the transmission to its normal position.

^ Install the transmission mount and crossmember assembly. Making sure that the reaction brackets are adjusted correctly.

^ Replace the exhaust intermediate pipes. Check transmission fluid level and top-up if necessary.

^ Check that the rear mount is centralized and free to move without disturbing the crossmember assembly.
