[EC900]

I agree - get someone local so if there’s any problems or tweaks needed it can be addressed under warranty.
The only problems I find is time…shops are backlogged with run of the mill stuff and rebuilding might be a secondary or “off-season” task.

Also, the 915 is an oddball trans and a bit finicky until you get used to the operation. 2nd to 1st is a common complaint. The leaks at the shifter rod seal caused the pool in the tunnel also common, so maybe you’re low on fluid or it’s just old if you haven’t taken the car on a proper ride, add some worn shifter bushings and coupler adjustment can also cause a miserable shift experience.
