My guy found an OEM transmission for my 01 4runner that had100k. The part cost $1200. They are out there on the location finder they use.
My transmission died because the lines were leaking. It was actually at the shop to have those lines replaced, we got a snowstorm, I took the truck back to plow, I couldn’t keep fluid in it and the rest is history.
The truck has 285K and I feel that warm fuzzy feeling knowing everything up there is replaced and that the transmission is Toyota. Runs like a dream too.
It never dawned on me until they mentioned it that transmission repair shops are almost non existent. They either find used or get a Jasper type reman which I DID NOT want.
if the pump is going just replacing the torque converter and pump is a band aid, you will need a trans down the line most likely. a friend of mine his trans was starting to go and he did just the tq converter and now about a year later hes looking for a trans.
if you can find a good rebuild shop thats always an option, replacing with a used trans can be hit or miss with what you get from a junk yard. there are still reman trans from teh dealership available and they may be lower price than you think
