checked outputs/inputs?
check shit before replacing parts.

"MOST" only know how to replace parts and hope that it fixes their problem.
ill hear some shit about this im sure

Re: DSM TCU Question
You are right to say that I should have checked codes first. I've seen some good faq's on how to use the multimeter and aligator clips. Another thing I have found stated that in problems such as this, leaky capacitors are sometimes the problem. I am trying to visually verify that to see if it is the case (if I can ever find the ******* thing)

Re: DSM TCU Question
I finally have a different TCU in, but the same problem I have been having 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.

Re: DSM TCU Question
fluid level does not cause as many problems as people think.
this is an archaic trans system, but it works just like most all trannies. but without seeing it...i am guessing.
but i still think you have a pinhole or crack in the case.
without pressure readings, i have no idea whether or not its a hydraulic issue or control issue.

Re: DSM TCU Question
Alright, went and did the diag with a multimeter. It seemed to flash real quick on a lot of random numbers but always seemed to build up to Code 11, which is Excessive Large TPS (Throttle Position Sensor) output. I am using an auto-range sensing multimeter, and I hope that isn't throwing my readings off, but 11 is the highest number it went to.
