Question about 1992 Mercury Grand Marquis
I have a 92 grande marquis and i was having fun in the snow like every other teenager in the world until it seemed like my tranny was slipping? I parked and checked and it has a reverse gear that works fine but the forward gear only catches once every few seconds and then it just slips again. checked the atf and it was fine. still slips when put into first and non-overdrive. did i just destroy my transmission or is there a simple fix to this?
Either your drive bands or your drive servo is bad in your transmission...you burned it up

There's a good possibility it's a transmission issue. The clicking is indicative that the gears inside are not meshing. Only way its repairable is to drop the transmission and once there, rebuilding it would be the next course of action. A used tranny would be less expensive but not by much and you never really know what you're getting. Sorry to be the bearer of bad news and best of luck to you.

do a filter and fluid change and add LUBE GUARD trans additive if this doesnt work,have trans repaired///sounds like valve body is stuck and this additive will fix it if thats the problem

1st let me explain how the transmission in this car is shifted, there is a computer control module, it is called the "Powertrain Control Module" or PCM, some cars have a separate computer that is just for the transmission, this is a TCM, your cars PCM does both jobs of running the engine and shifting the transmission. The actual shifting is done by electric solenoids inside the transmission which the PCM controls by grounding them, when the computer determines it is time to shift based on vehicle speed and transmission fluid temperature and other inputs from the engine sensors it grounds the proper solenoid that shifts the transmission up or down to the appropriate gear, it monitores the shift electronically and if it doesn't see that the transmission has done what it was commanded to do it sets a fault code in its memory. I have read your problem and no mention is made that "Your Mechanic" scanned the system for fault codes, if he did and nothing shows up then you have a mechanical fault in the transmission and it will need to be torn down and rebuilt to correct this shift problem.
My experience is 25 years as a Ford factory trained repair and diagnosis technican.
