Replying to: psi4757 (Mar 02, 2008 6:14 pm) Not good at transmission problems but the fluid burned up the seals around the Torque converter. The transmission will have to be drop down to inspect the seals in this area. I'm sure you checked the fluid and it was burnt smelling. Transmission must be(running) when the car is moving down the road. When running, it keeps the fluid pumping through the transmission and out to the cooler up by the radiator. Its like you running your engine and had the water pump disconnected. The water wont circulate around the engine and out to the radiator if the water pump is not running too. The transmission operates the same.When the car is moving, the transmission Torque Converter is actually moving too! The force of the rear tires instead of the force of the engine is turning it. This creates a hot condition in the transmission because the engine is not running the oil pump in the transmission to keep it cool. The Torque Converter is like a couple of fans that face each other. Throw in some transmission fluid and you have force from one fan driving the other fan. The force from the engine drives the other fan connected to the rear tires via the fluid, no mechanical contact. In your case the engine side was not running it also runs the pump I was mentioning above. The fluid from the rear tire side got hot when the engine side was acting like a restrictor for the flow of oil out of the transmission.. Now you know, to leave your engine running if your going to tow your car any length of time. The tow people should have told you to keep the driving wheels off the ground or disconnect the drive shaft that goes to the rear wheels from the transmission. |

I dont believe its the battery cause it turned right over a few seconds later when i got it in the garage a little crooked and started up again to realign it . Done this once before . I 'll check amp draw during start at the Autozone when I get a chance. |

I just became the proud papa of an ultra clean '94 Q45. Here's my dilemma. The car has broken the driver's door locking mechanism. It has now gone into security "shock". I did get the door to "lock" itself, not that I could tell, and when I opened the door it went bonkers. Long story short, I cannot get it to turn over. I have tried lock/unlock with the key and so forth. My key fob beeps at me, it will not operate anything on the car. I really don't want to mess with the rip offs at the dealership. I'm pretty mech inclined, just need a shove into a right direction. Your help is GREATLY appreciated..!! Chad

Replying to: cowbysingr (Jun 04, 2008 10:21 am) I can get in to my wire diagrams on my 1990 to see the logic in the wiring for a door lock broke.It could have energized the cutout starter relay. I've seen something labeled cutout once I believe on mine. Sometimes I remove the battery ground connection, it wipes out the memory in the computer. I guess kinda like the Restart button on computers. Does the hood release still work? |

Hi all: My '92Q has developed a loud buzz in the rear speakers. It does not vary in intensity with engine speed and the radio/CD/Tape still plays through them, but the buzz is loud and constant. it doesn't matter if I'm tuned into a radio station, or set the radio to no statio, the buzz persists. Fading from front to rear or changing from left to right balance also has no effect. I'd change out the rear speakers, but don't want to do that if the probolem might be in the head unit. Any thoughts?THANKS! I miss my tunes.
