Continuing TRANSMISSION problems - Toyota Nation Forum : Toyota Car and Truck Forums

I have posted transmission questions before and I got a lot of help. I appreciate that. However, I have a new problem. The sort history of this problem is:

Replaced transmission with one from a salvage yard. Did not work in reverse. Could not turn it back in because I went over 30 days.

Swapped out transmission with one from Pick 'N Pull. This one is worse. If you push the engine to high RPM it will creep forward (or backwards if in reverse), it is almost like a slipping clutch for a manual transmission.

Could this be a clogged filter? or something external to the transmission? I am now at the point that I can pull the transmission in about 3 hours. However, this is getting ridiculous. Any suggestions would be appreciated.

The best thing is to attempt to build one good from three bad ones.
The good used transmission is only the one that is pulled from running car, not the one that seats hell knows how long on the salvage yard.
The 15 years old used tranny is a huge risk to take!
I am overfilled with poor quality of used units, and that's why we gonna to retire our camry after the next smog ( which it will fail due to the visible smog non-complience)

How difficult is it to rebuild a transmission? I have no experience at that.

If you have factory service manual it explains the steps pretty well.
The components are stacked up inside the housing and closed off by the front pump.
After front pump removal most of the inner parts are just sliding out of the “tunnel”
You may need the caliper as checking the clearances and part sizes is important for the proper function and long life after rebuilding
Only few shops actually doing that, the local rebuilder down the street does not know how to use the caliper, but he knows how to milk his customers.
Second, take snapshots before doing the next step.
The proper alignment of the Teflon sealing rings on the input shaft and the front pump hub is critical during the assembly otherwise thy may be damaged so mark their position.
Do one gear at the time, because parts are very similar
That’s the basic rules.
If I will live close to you I could give you a hand on this task.
