ECT = Engine Coolant Temp I should have known that. (feeling stupid)
I was told the ECT was the same on both engines so I did not change it.
Do you think it could be that easy? Or is it more likely in the tranny?
My friend has a snap on scan tool so I hope we can put it on this weekend.
I will look over http://www.williamwren.com/Bonnevill...umba/page1.htm
as soon as I get some free time
Thanks to all

Update: Called the friendly neighborhood parts man to find out if the ECT'*
are the same for both engines, and of course they are.
Next is the scan tool, sure hope I find something there.

Well, I wasn't really leaning towards a faulted ECT. If the ECT was faulty, it would have probably manifested itself through other symptoms. The other thing that comes to mind would possibly be the transmission fluid temperature sensor input to the PCM. If the transmission is overheating ( high fluid temp.), it'* my understanding that the TCC will not apply. But the scantool will tell the story. Good Luck

I have the 'No OD when warm' problem in my 1994 SLE too. But I can work around it though. I go about 5-10 mph over the desired speed, shift into neutral, shut the engine off, open drivers door (just enough to shut electricals down), restart, shift into OD, and use the cruise control to adjust speeds. Once I hit the gas or the brake it drops out of OD, and I have to repeat the process.
Anyhow, you can be sure I'll be watching this thread (wish I had more useful input) as it may help me to solve my problem also.
Good luck,
Martin

Hey BlueEyesBonne, when I first bought my 94 SE, I had the exact same problem. When I first got into OD, it would lock the TCC for 10 seconds, until the computer recognized that the tranny was slipping something terrible. Then it would drop back into 3rd gear until I power cycled it (basically, just leaving the car in drive and flipping the key off and back on fast enough so that it would power cycle the computer but keep everything spinning). The only way I could keep it in OD was using cruise control.
Fortuently, the dealership I bought my car from had a 7 day warranty....since they had to buy me a new transmission to fix the problem...

Hmm. Mine has not been slipping at all and the fluid is clean as can be. I had the codes read and got the codes for the Quad Driver Module A & Quad Driver Module B (both of which are part of the computer so I need a new ECM), and a code for the TC Lockup solenoid. I had a total of like 4 codes, the other being the ignition module.
Hope to have the new ignition module and ECM in the car in the next 2-3 weeks (have to if I get the SSEi sold by then -not getting many hours (-$) at work so have to sell the SSEi as I think I should head back to College).

Each of the Quad driver'* monitor 3 or 4 other engine sensors/parameters. It'* possible that the PCM is fine, and you have other problems. Consider the QDM'* as 'hub'* for other devices

Please give us the exact code numbers.
