TR2/3/3A tr3 overdrive-toast

[sp53]

Here is a difficult post to answer without seeing the car, but please take a shot. I am looking to buying a tr3 overdrive, but the car was involved in a garage fire and was pulled out by the firer department. The car is totaled, but not that bad. The tires are still holding air; the glass on gauges is kinda there. I am wondering what inside the tranny could have been ruined beyond repair. I can see the seals being toast, but is there anything on the overdrive that could not take a little heat. It would have been under the car and not had the max temps.

If the tires made it, I can't imagine the OD being bad. After the rubber parts, the case would be the next part affected, as the cast aluminum would be next on the temp scale. It would soften above 400 degrees and warp above that. So, if the case made it unharmed, I would think the internals would be good.

No problem, had a friends melt the steering wheel and warp the bonnet and all was fine on the drive train.

Look at the solenoid and the sw's on top of the shifter. They could be damaged but even if they are the inside of the trans should be good.

Might be worth just replacing them anyway. They're a pain in the anatomy to change after the car is back together.

Unless you know the history of the OD, I think you would save a lot of time, effort, grief, and money by testing and/or disassembling for inspection before installing it. It will never be easier to replace gaskets, seals, o-rings, and inspect the sliding member for wear. The same applies to the trans.
See you at Tacoma?

At the very least, spin it up and check the pressure. Even if not damaged by the fire, it may have been on it's way out before the fire.
