I was about to perform some transmission service on my '04 GTS. Come to find out this is suppose to be done every 30,000 miles. All the shop manual mentions is that you flush and fill the fluid. Says nothing about changing the filter.

For good reason too. In order to change the filter on the F4A4B (4 speed), you have to remove the transmission then remove the torque converter housing from the trans to get to the filter.

If you let the maintenance slide on your car, this is what the dealer (or someone) will end up doing. I can't imagine the cost involved in R and R'ing any of these transmissions.

I usually do all my maintenance and repairs myself, but there is no way that I am going to remove a transmission just to change a filter. Nice thinking on Mitsubishi's behalf there.

WOULD CHANGING THE FILTER BE COVERED UNDER THE POWER/TRAN WARRANTY????
