1996 Explorer, 4WD Automatic 4.0.
Had the transmission replaces a few months back at a reputable shop locally.
Everything runs great, except when over 80-8h MPH. When you get to around 85mph, the car will randomly "jerk".. It feels as if the transmission is trying to downshift for just a split second and then decides to change its mind and shifts right back before engaging the lower gear.
This happens regardless of driving uphill or with/without any load.
The transmission shop has updated all valves and whatnot that apply to this year (or so they said). They have mentioned they really cannot do much for me (regardless of warranty) since this happens at speeds over 75mph.
Perhaps it is worth mentioning that every once-in-a-while the OD light comes on and flashes. The past 4 times this happens, I took it back to them and the owner has said it is a "Torque converter lockup failed" error. The torque converter has been triple checked - as has the entire transmission and he cannot find anything wrong. To quote the owner at the shop: "it is as if the computer is reporting a problem that does not exist".
A couple other notes:
1) As mentioned, the "torque converter" issue has been detected in the computer. What re-enforces this is the fact that every once in a while - at highway speeds - the engine WILL rev up a bit (as if the torque converter is unlocking). This happens rarely but at random. This also happens regardless of flat roads or uphill. Once again, the TC has been replaced and triple checked.
2) At first there were several errors reporting (causing the OD light to blink) relating to the VSS. Once again, a new sensor and several close checks to the wiring revealed no fault. This also happened after the tranny was replaced.
3) I have read a handfull of accounts that mention re-programming the ECM has solved a number of rare quirky issues after transmission work. I also read somewhere (here in fact) that there was a TSB issued on flashing OD light issues after transmission work (re-calibration?). I have contacted the local authorized Ford dealership and they quoted me around $75 to re-flash/re-program the ECM.
Anyone have any ideas? The transmission shop is clueless and since it drives fines under 75mph (with the exception of the rare flashing OD light), they can not do much more.
