I must say it's working and my Transmission is going into Over Drive almost all the time.... This 2001 Jeep Cherokee XJ Transmission was in a Flood and a lot of the Components were affected. My Jeep is still throwing a P0740 Error Code and this module can be one of the Many Causes, So I bought it. I'm addressing the other causes. But a bad Symptom associated with a dying TCM TCU 56041386AB Transmission Control Module is very poor Gas Mileage. With that said my MPG I've seen a noticeable Huge difference. So as far as I know It's great. The only reason I gave 4 stars is the Jeep isn't fixed yet.... I wonder if these People will take the defective module and refurbish it...... I think if you need one Buy from these guys......

We found out from our mechanic who installed this part that it’s faulty. I know we bought used, but just disappointing.

With the 2 codes I had this tcu was top repair although it wasn't the cause of the problem , wires were shorted out in the wire harness, had to eliminate it the box as a part of diagnosis, I am going to keep it because it is a discontinued item and is only going to get harder to find in future
