I have a 92 Ford Thunderbird that will not shift into reverse or drive. We changed the tranny fluid and the filter. We let the fluid warm up and then took it for a spin and it was still not shifting into those gears. The only thing we haven't done is ripped the transmission out.

line? not sure what u mean by that , ford trans in a 92 is shifted by fluid pressure , if it wont shift 1-2-3 then its got a fluid flow problem , now if it will go 1-2-3 but wont go 3-2-3 when passing that's done by a vac hose
about the simplest/lowest cost and easy thing to try is to change the trans fluid/filter first !!
Is this an automatic? I can't tell if column shift or console? With column shift, Did you try taking shift linkage loose from tranny and shifting by hand? There are safety issues with trying that, make sure functional parking brake is set and the wheels are blocked. Also, have a helper sitting there with foot on the brake. Safety is your responsibility.
Maybe just a tranny issue, I'm not a tranny person.
You might be able to start it and kill it in drive? There are safety issues trying this and I don't want the responsibility. Safety is you responsibility.
Really dirty tranny fluid. As it gets warm, the viscosity (resistance to flow) lessens; the fluid gets more watery. When that happens, it can lubricate the gears and other parts more easily. When it's cold, the fluid is probably too thick and sluggish to move.
IF this is a automatic the tranny is bad and your check engine light should be on. Future advice all tranny fluid should be changed at 30 to 40 thounsand miles,,,,,,,,,,thats why we are seeing so many bad trannies
If the trans has a whine and shifts a little hard then you need to take if to a service center and have the trans flush and filter changed this might correct the problem. But if you have never had the trans fluid change and have 100,000 on it trans might be going bad. Trans fluid and filter should be changed every 40,000 miles.
It is usually the electronics of the transmission. If you don't have any other symptoms, you may be alright. If you are getting slipping in between shifts, delayed engagement when put in reverse or drive, these are signs that the internals are going bad.
try some transmedic .put a little in tranny .try to take out some fluid add it in dont over fill transmission .put about a half of bottle in it. it wiil loosen those stuck shift valves.
I had one of these cars and loved it - this is happening around 45 - 55 mph trying to go into overdrive, you have to change the fluid and filter, those tranny's MUST have their flud changed every 9-12000 miles, make sure you drain the torque converter as well when changing the fluid, the gasket on the pan is reuseable - replace the fluid with this mix - half B&M trick shift which helps preserve the bands and clutches and what not - the rest just use a good brand of DEX MERC, happy motoring
