We put in a used Motor that was from a standard transmission vehicle, into our Automatic transmission vehicle. We used all the automatic harness apparatus along with the automatic ECU. Now the new motor runs smooth, but the transmission will not go into any gear. The cable is moving as you check underneath when someone changes gears. Any suggestions as to what may be the problem?

 

Did the convertor fit into the crankshaft ok?
A standard transmission has a pilot bushing and the back of the crank is smaller lots of times.
Remove a cooler line at the rad and fire it up.

If there is no fluid flow the pump has been compromised.

 

The converter seemed to fit the crankshaft okay. We have now removed a cooler line at the rad as you specified and fired it up. There was NO FLUID FLOW. So now our question is What pump are you talking about that has been compromised? Is it a pump inside the transmission? Or where is this Pump??? Could it be that the torque converter is not pushed in all the way??? Please answer us as soon as possible.

 

The pump is inside the transmission.
If the drive flats on the convertor weren't properly aligned with the driven flats in the pump the driven gear will be forced into the stator support and destroy itself within a few seconds.
You will have to remove the pump.

 

Thank you for the earlier reply. It appears that we did not put the convertor in correctly the first time. As you now say the driven gear will be forced in to the stator support and destroy itself within a few seconds. Do you mean that the stator support will be destroyed and you have to remove the pump to get at this stator support? Or do you mean that the pump itself will need replacing? Are you able to explain to us what needs to be done to fix this situation? Thank You,

 

That is correct.
The entire pump will probably have to be replaced.
But that is now only a small portion of the problem.
There will be oodles of fine metal particles from both the stator support and driven gear that have been circulated throughout the transmission because you have been driving it.
The entire transmission should be stripped down and the metal particles cleaned out.
Plus the convertor will be toast and the cooler and lines will be contaminated.
Good luck.
