3000GT VR4 / Dodge Stealth AWD Transfer Case Input Spool Replacement

The input spool on the 3000GT / Stealth AWD Getrag transmission/transfer case setup (W5MG1 / W6MG1) is very prone to corrosion and spline wear. Anytime the transfer case is removed the splines should be cleaned and have heavy grease applied to both the shaft coming out of the transmission (output shaft) and the splines inside the t-case, the spool as we call it.For those that do not work on these units often it may be unclear what to [...]

3000GT / Dodge Stealth Transmission Shift Fork Roll Pin Walk-Out

3000GT Dodge Stealth Output Shaft Wear

In order to cost effectively offer both a front wheel and all wheel drive option Mitsubishi used a transverse layout for all 3/S cars. With the engine “sideways” in the engine bay this meant that somehow the power from the transmission needed to go back towards the rear end and make a 90 degree turn.Mitsubishi’s solutions on the 3/S, DSM, and EVO cars are all slightly different, but they all consist of a centrally located transfer case that bolts [...]
