This Service Information bulletin supersedes S.I. 23 03 99 dated March 1999 which should be removed and discarded from your S.I. binder.

SUBJECT:
Exchange Manual Transmission - Oil Specification

MODEL:
All Exchange Manual Transmissions for Current Models

Situation:
All exchange (replacement) manual transmissions produced from 9/97 are filled with the new lifetime oil designated MTF-LT-1.

This means it is no longer necessary to perform oil changes on these transmissions.

Note:
The only exception is the E39 M5 (862) which requires a transmission oil change at the 1200 mile service and 1200 miles after a transmission replacement.

All manual transmissions filled with the new lifetime oil are identified by a yellow label located near the transmission oil filler plug which reads "Lifetime Oil MTF-LT-1".





Vehicles Affected:

Parts Information:
Lifetime transmission oil (MTF-LT-1) is available under BMW part number 83 22 9 408 942 (5 liter container).

MTF-LT-1 oil only needs to be replaced or topped off if repairs are performed on a transmission and replaced on E39 M5 (S62) at the 1200 mile service and 1200 miles after a transmission replacement.

A hand pump has been developed to aid in filling a transmission with MTF-LT-1 oil and is available under BMW part number 90 88 6 002 080. Refer to service information bulletin 04 03 99 for further details.

Note:
MTF-LT-1 must never be mixed with other oil grades since this would no longer guarantee the lifetime qualities of the oil.

Warranty Information: Information only.
