I have a 95 4x4 auto, that just slipped out of forward gear in an intersection , and would not go into any gear after that,,,, except park ! I have searched this site and have noticed a lot of similar problems, usually the trucks will go into at least one gear, but not mine.I found a video on youtube last night where the guy said that this is common problem on the rangers and it's a blown/torn valvebody gasket.
He removed the pan, filter , valvebody and spacer plate, and both valve body gaskets were torn in a couple places and spitting the gasket out of the side of the valvebody. He said this causes fluid pressure loss, and it starts out being lazy going into gear, and escalates to not engaging at all. I am pulling my trans pan tomorrow, and seperating the valve body, so I will post what I find. I read several posts and all I really learned , is TRANNY IS SHOT !!!
This may still be the case, but I will tear it apart and check the gaskets , and troublesoot till I find the issue. Has anybody else gone thru the troublesooting process ? Any Pointers ? Thanks, bubs440
