I would like some quick telephone advice ASAP. If I can call you please email me your tel #. TIA  SignatureRoy rem NADA to reply If not, could you please give me your opinion on my other posts in the thread: "94 Ranger problems (tranny and now white smoke?)" Is there something fixable or do you think I also need a remanned transmission. SignatureRoy rem NADA to reply |I would like some quick telephone advice ASAP.

They changed the defective modulator, dropped the pan again showing no visible debris, charging me yet another hours labour. Said the fluid looks dark. Where it used to shift hard up and down a little above 20 MPH before we started everything - it now slips. RPM's seem higher all across the board, then again that could be my imagination. A couple of times I hear some chattering under load, more often in reverse. Mechanic is telling me the tranny just died and needs rebuilding - has nothing to do with his changing the fluid and the modulator. Is just a coincidence. The truck is at 68,000 km. I've towed a uhaul trailer once in the last 2 years, don't try to burn rubber or do any off roading. The previous owner did not seem the type for that either. I am just a little miffed that some preventative maintenance seems to have started this all off. I've noticed in the Ford service manuals that one can adjust the bands. When would one normally perform that service? Would it help here? I am confused. I thought following your suggestion of a partial fluid change would be good for the truck. Is it normal for the A4LD to just start slipping that quickly? I know it is hard for you to say without seeing or driving the truck. But if there is something I can try and report back to you then I will. Can you recommend a site that has a good description of the basic workings of an automatic transmission so I can get a better understanding?

It is about 40 minutes away at highway speeds. Would you think it is OK to drive mine that far, or should I get it towed?

Said it was virtually impossible for 2 modulators to go within a tank of gas. So he pulled into the mechanic he knew to get a second opinion. They popped the hood, pulled the vacuum line, smoke stopped and engine levelled out. Turns out the 1st garage dropped the little pin the modulator valve moves, this in turn, was causing the diaphragm to blow. They had a pin on hand, installed it with a new modulator and more fluid. So 3 modulator valves and partial fluid changes later, I've still got a hard shift up and down that I guess I'll have to live with. Carrying a lighter load in my wallet doesn't seem to make any difference. Do you think tinkering with the adjustment screw on the modulator valve might help? Thank you for all the help.
