One more A/T TCU Question

[Sickinger]

Thanks to everybody that provided the information I needed over the last couple of days to change o9ut my TCU in the car. I finally have a different one in, but the same problem occured again. If you start off at a red light or stop sign, the car shifts perfectly and it runs great. The problem occures two different ways that I can see. First, when the car is up around 65-70, the car will fall out of O/D and limp mode is engaged. Second, on some stop lights, the car will just not shift back to first and will stay in second gear. Both problems temproarily resolve themself when the car is turned off and on, just screaming potential computer problem. I have a theory though, and I want to see if the guru's here may be able to provide some insite.

A. Is it possible that the transmission fluid is wrong, or at an improper level (even though the stick says it's good) causing the car to not hold O/D and by bringing the car down a gear, the TCU senses the problem and puts the car in "limp mode" to preserve itself?

B. I have seen mention of something to do with a speed sensor. Would this be a potential problem, sending improper information to the TCU, causing the car to be placed in "limp mode"?

Thank you for any and all assistance.
