AWD Automatic and MTX DSM & Mitsubishi GTO SR Transfer Case Rebuild - ( rvengeATX-MTX-DSM-W5M31-Tcase-rebuild )

After many years, miles, and launches the DSM / ECLIPSE transfer case often needs some maintenance. The spool design of the transfer case allows for corrosion to slowly get in and wear the teeth on both the splines of the transmission output shaft and the input sleeve on the transfer case. It is important to replace these in pairs when possible as mixing one worn set of splines with a new one will lead to a sawing action and rapid wear.

This rebuild includes:

• Full cleanup and disassembly of case and internal items.
• Installation of all new seals and sealant
• Inspection of both the pinion bearings and spool bearings. If pitted or worn bearings are found they will be replaced.
• Verification of bearing preloads, pinion pre-load torque, and gear tooth pattern.
  • New Spool Freeze Plug Seal
  • New Grade 10.9 Bolts
  • Leak and spun test before shipped out

We are proud to offer optional REM surface treatment now!

We also offer optional WPC treatment for your gear set. The gears are known for shattering under hard launches and this should prolong the life of your gear set. For more information please visit WPC

Our cores include a good or new standard strength spool.

Please note your transmission output shaft must be replaced or new for warranty purposes (regarding spool wear only)

This is a rebuild service of YOUR core.  You will need to send your core into us prior to the rebuild. If you do not have a core, you must select the core charge. The core charge is NON-REFUNDABLE.  If you would like to send a transfer case to us after purchasing a core from us, we may purchase your unit from you. However, its value will not equal the core charge
