Ranger Transmission Problems

Hey all,

Working on a 91 Ford Ranger with a 4.0 in it. We have replaced the clutch, pressure plate, throw out bearings, a cylinder pump? the clutch master cylinder and the neutral safety switch. But, it's still doing what it did to start with.

It doesn't want to go into gear when the motor is running. When the motor is off it switches fine. Also when you switch it while it's off and put it in first or reverse, then start it, it tries to roll forward, like the clutch isn't releasing.

We've replaced everything we can think of. Is there some kind of sensor or vacuum that would cause it to not change once the motor is on and it's loosing pressure that way? After replacing everything, the clutch has built up good pressure.

Thanks for any help.

Welcome to the diy forums!

I don't know much about hydraulic clutches but on a standard clutch I'd check the linkage adjustment.

Thanks for the welcoming. I'll check those, don't really know much about it either but tried to replace the main things one by one to eliminate the problem, to be alot of money in and at the same spot lol.

It could just be a matter of air in the system. If you have a bleeder on the slave (and some don't), pump it up, bleed it, close bleeder, pump it up, repeat.

If there is no bleeder on the slave, fill the master, leave the cap loose to let air escape and pump, pump, pump. It takes a while that way to get the air out, but eventually you will.

Hope this helps,

Bob

Problem is the design of the clutch master cyl. It points downward, the hose to the slave is at the bottom, leaving an air pocket towards the firewall that will not clear ..........Disconnect the master cyl and remove it from the firewall..........It should have a remote reservoir, so turn the cyl till the hose is higher than the rest of the cyl.........Then bleed from the slave.......reinstall the master and your problem will be over
