Al of the gears wont work. It feels like it goes into gear and the motor even changes sound when changing the gear but the car does not move. I know a bit about transmissions and i know that all the gears would not go out at the same time. I have checked the transmission fluid and even replaced the transmission filter but still nothing.

It could be the transmission fluid pump. NOt supplying pressure to the shift solenoids and transmission drum servos. Not many times ive seen it but it happens.I have also seen the pump drive shaft that turns the pump , the teeth on it wear down to where it is unable to turn the pump. Not alot but have seen these things on the F4A42 transmission

I was thinkin it was maybe a sensor or one of those pumps you mentioned. But what cost more, to just replace the transmission or to try and find all the problems?

On the car. Unlike previous series , the F4A series and up all have the pump on the rear of the transmission case, like most of Mazda's transmission and can be accessed frum the left side fender well. The under cross beam needs to be removed , and the upper transmission mount , while the transmission is supported by a jack and then slightly lower it to access all teh retaining bolts around the pump to case housing. Its kinda a tricky thing to do and i would not designate a novice to do it. But seems yu have nothing to loose. Wish i had a diagram for yu but at the moment i do not . But will try and get one for yu.

[right][snapback]188327[/snapback][/right] you dont know what you're talking about. the trans in his car is either a 40 or 50 series, depending on whether it has a 4 or 6 cylinder. and the oil pump for it is driven off the torque converter, just like ALL mitsu trannies have always done. unfortunatly, there are 2 likely failures. the most common is that the wave spring for the low/reverse brake shattered and has been ingested by the oil pump, destroying it. the other is that the planetary gearset has suffered a catastrophic failure. certainly something else could have failed, but you're gonna be looking at a trans overhaul or replacement more than likely.

F4A40/41/42/43/51,F5A50/51/52 all have the pump on the outer rear case of the transmission as opposed to the folder F4A3 and down series I never said its not driven by the TQ convertor, no where did i say that. The F4A4/F4A5/F5A5 transmission series has the pump at the rear of the transmision housingas opposed to the older model units with it generally right after the TQ convertor. That was wut i was stating.

Directly next to the torque converter. Mitsu has never released ANY automatic trans that didnt have the pump located directly next to the converter.

Its housed in the rear section/second section . That and the encorporated rear removable section are part. And the rear drums are removable out of the back of the housing. To which yu can inspect the inner shaft and drum sealing rings. Best thing is to replace the transmission.
