MPV shift shock. This will be fix by having transmission control module reprogrammed at the dealership.

yes you can have just the bad shift solenoids replaced . you do not need to replace the transmission

Was there a problem BEFORE the maintenance or only after?

Car is running in 'limp mode' so it won't drive correctly.

Did you have to pull the dash to get to heater core? IF so, something's still loose back there.

My Mazda MPV 1997 OD light flashes and engine light is on

Most transmission shifter ( where you shift) has a linkage control to shift gears in the transmission. Those joints from the linkage have bushings made of rubber. Once these rubbers were worn down and torn, the noise from metal friction from linkage can give you that intermittent noise. When the gap from the linkage joint enlarges in lieu of the bushing space, it causing the engagement of shifting is off from original position that was why you are experiencing "binding in other gears"
Have a different shop to check out these linkage control bushings and replace them. The bushings are cheap and it probably takes about 2 hours the most to replace them. This will save you a lot of money on spending on unnecessary repair. Good Luck.

This is a known issue with certain '03 and '04 MPV transmissions; my 2003 had the same problem. There is a Mazda technical service bulletin about this - 05-003/004 (Shift Shock). You need to take the van to a qualified shop and have them flash the transmission control module (TCM) with new firmware.

I had this done. It did not completely fix the problem but it did reduce its occurrence.

yes that is your OVER DRIVE light do you have it in OVER DRIVE or regular "D" for drive is it shifting okay?????maybe see garage who replaced your transmission maybe something not plugged in proper! hope this helped you.John

I had this problem a few years ago. Get it checked out right away. I didn't and I ended up having to replace my transmission.
