My 25det auto trans decided to spit the dummy

As being a frequently used vehicle, and shipping on my manual conversion taking it's time. Thought I'd slap in a 20det box in the meantime as theres one sitting in the back of a mates shed. 

But after pulling the 25 box out I found that the output shafts are different, and my mate doesnt have the driveshaft with the 20det box. Before looking for a 20det driveshaft, was wondering If there would be any other issues other than the 25det and 20det output shafts being different. Will I run into length issues or anything. Or should it bolt straight up.

How about....the TCU not being interested in running the wrong trans?

Ecu had no problems running a 25det box in the months before hand.

TCU means Transmission Control Unit.

ECU does not mean "Electronic Control Unit". It rather explicitly means "Engine Control Unit", despite what the Gen Ys and Zs would like to think.

My original comment a few posts above was based on my thought that the R32 and R33 auto trannies were not the same gearbox and did not work with each other's TCUs.
