I've been having some occasional transmission problems with the AOD in my 1986 Bronco w/302. The two main problems are briefly described as follows:
1) at highway speeds (sometimes slower) and under somewhat of an upgrade, the transmission feels like it is slipping out of gear... but it never really downshifts. it may do this 4 or 5 times in a row and then continue on like nothing happened.
2) at times while stopped with my foot on the brake and the transmission in Drive (such as at a stop light), I can feel the engine idle drop for a moment while a feel what seems to be the transmission trying to engage. (the engine idles fine alone in neutral or park)
I told this in greater detail to a transmission shop and got a free road test. Of course it did not have any problems during the test! (maybe it happens only when the fluid is warm?) Anyway, I was told that the Torque Converter is most likely the problem.... its having trouble staying locked at high speeds (causing problem #1) and at a stop, the converter may be locking up when it shouldn't (causing problem #2).
This seems to be a reasonable diagnosis... does anybody disagree? Does anyone know the size and specs a factory AOD torque converter? Any idea what I should be paying for a new one and have it installed (assuming nothing else is wrong with the transmission)?
