testing autos

Is there any way to test a tranny without installing it or taking it to a shop?

The only way to test a transmission out of a car is with a transmission dyno. That's a very complex and expensive piece of equipment. Most big remanufacturers use a trans dyno to test their units before they ship them.

I guess you could rig up an electric motor to turn the input shaft. But I don't know how fast or much torque would break the trans.

That wouldn't be practical. You need a load on the output shaft and a way to bolt the transmission securely.

practical is for sissies. just rig it together and blame the neighbors if it goes south. I don't know what extra parts you have lying around but you can figure out how if anyone can. Also, if you can get the torque converter back on, turn it and shift it by hand. That might give you a better idea. Have you checked the pan to see whats in there? My last thought is to lift up the front end of the Bronco, rig up some adapter from one of the hubs to the input shaft and engauge the 4wd. Weeeeeee! Wear body armor.

Naw, this is for a few autos out at my grandmothers, I don't feel like stuffing them into a rig just to figure out they're no good.

Remove the pan and look for any debris.

Turning the input shaft won't do diddley squat. It's the pump that must turn and you need to turn the convertor faster than 800 rpm's to get pressure.
