Tranny prob ?

[kev_1669]

My family owns a '94 E-350 Club Wagon 15 Passenger(1 of those church vans) We bought it becuz it was deal we couldn't pass up.

351 Windsor 150,000 miles 4-speed auto on its second transmission

When my dad drives it he drives it like a baby, to conserve gas.
My mom would rather drive it than the new Saturn my dad just bought for the around town car. Before we got an old car for me to learn how to drive, we drove the van around town. So now my dad drives it to work.........

In the last few months we have been having probs w/ the tranny.

It will just slip in N for no reason going down the road @ 65 or any speed. It will slip and we can sit there and rev the engine and then it will jerk back in gear. It will also JERK into the next gear when shifting. Somtimes it does this and somtimes it will drive as good as new.
Somtimes when it does it, we pop it in N and cut it off(while going down the road) for a few secs. and the restart it and it will drive good and sometimes it will start doing it again.


We have already had it looked at twice. The tranny guy checked the fault codes that were in the computer and it had a rear end speed sensor fault in the computer, so we replaced the Sensor and it still did it, so then he dropped the tranny oil pan and it didn't have 1 sliver of metal in it. So now the guy told us it was either a new tranny or a new Computer. Both being $1500-2000.

I told my dad that it was the computer from the begining, but we r not sure. My mom won't even drive it. I am not even allowed to drive it and my mom made me drive it the other day becuz she freaks out when it does it....LoL.....


Anybody got any suggestions or any experiences?

well, the comp is a possabality...

have you checked the fluid levels once its really heated up?
and also, when the pan was droped, did your mechanic check the valve body for anything that could be out of place? Hell, just too much dirt in the valve body can cause this because fluid wont make it to all the right places and provide pressure so it would simply fail and go to N.

In any case, ,good luck!
