QuestionQUESTION: Hi again. You said something about the torque converter might not be in place. My Son just told me that when he was bolting the fly wheel to the converter, the converter moved about a 16th of n inch toward the engine. In my days of changing rear wheeled transmissions, the converter was not suppose to move. Is it the same case for the front wheel drive tranny? As I said before, no matter what gear I put it in...nothing..no movement at all.
Thanks again for all your help
ANSWER: Hi Dan,
If the old and replacement trans's neither would drive I would suspect the converter. But on the detail you menitoned I am not familiar. Have you verified the fuses 2,10,12 in the under dash fuse box. and fuse 15 in the underhood box are OK? A code reader would be helpful to see what the TCM thinks is the matter. You might try the 'on-off-on-off-on and leave on, in 5 seconds or less' to see if any code numbers show up on the odometer window, but that is unlikely. You probably need to plug in a reader.

QUESTION: HI Roland,
I might not be explaining myself correctly. Before you install a Transmission, you have to turn the Toque Converter several time clock wise to seat it into the Transmission. It should not be loose or fall out. Am I correct on that. If so it may appear that while My son was installing it to the engine, it came loose again. When he was bolting the four bolts up, he said the Torque Converter came forward towards the fly wheel. Only about a 1/16 of an inch. The Transmission was already bolted in place. I hope you can understand this time.
Thank you for your time. Yo have been very helpful so far. I'm not where the Van is, so I can't check the fuses.
AnswerHi Dan,
I can't understand why 1/16 of an inch would disable the function of the torque converter. Maybe I midlead you on that as the focal point for your 'no drive'. I would expect though that if it wasn't spinning that you would not have any internal pressure in the hydraulic circuits because the torque converter also 'drives' the transmission pump. So you could verify whether or not you have trans fluid pressure at one of the test ports as a proof of at least the internal rotation of the input shaft of the transmission. If that is happening than the 'no drive' would not be related to the torque converter.
I still would want to know of any fault codes that the tcm might show that would explain the no drive. If you don't know the history of the replacement transmission then checking for debris in the pans, and if that is absent, removing and cleaning the valve body is suggested by the manual when you have a 'no drive'.
