If its a standard trans, its fine. If its an automatic, its probably f*cked.
He towed yours or someone else's?
that sucks if its an auto
yea its an automatic
Well there isn't but one way to find out, and thats to drive it. Most likely, its ****ed though.Originally Posted by DaRussian
yea what sucks is that it doesnt drive, im changing the engine on it right now, and i need to know should i go ahaed and change the tranny too? but its expensive as hell
he towed it in park...? or in neutral? if it was in neutral its fine. and if it was in park it woulda drug the tires the whole way making it near impossible to tow.

You obviously don't know how an automatic transmission works. It is nothing like a gear box (manual transmission). A gear box is all mechanical engagement, an automatic works off of hydraulic pressure.
A gear box is lubed by the counter shaft slinging fluid throughout the transmission, much like a crankshaft's counter weights lubricate the cylinder walls, and piston pins in an engine.
The only way an automatic transmission is lubed is when the pump is turning, which only happens when the engine is running. If the pump isn't pumping, there is no fluid circulation, therefore it cooks the the planets (gears), sprags, drums, clutches, etc....
As far as it being in park, you are correct. If it was in park, it would drag the tires, and probably eventually break the parking paw, paw gear, or output shaft.
When the engine is off, it makes no difference in an automatic transmission which gear it is in for the car to roll, just as long as it isn't in park. Everything works off of hydraulics except the park function.
Pull the pan on the transmission, and see what the fluid looks like. If it isn't burnt, and if there isn't anything out of the ordinary in the pan, I'd try it. If the fluid has a burnt smell, or if there is debris in the pan, go ahead and save yourself some time and just replace it.
