Mt565B not shifting.

Needing some help have a Mt565B doesn’t shift out of D range. Does move but won’t shift down. Had tech come look at it said there were two pressure sensors were bad changed them out but still same results. Got back in touch with tech but he hasn’t come back out Recieved a $3000 bill haven’t paid it yet since they didn’t repair it. Tach doesn’t show rpm’s hydraulics lift doesn’t work. Could it be a computer problem?

Could be your controller, or wiring. Had a similar problem with Massey 7495 CVT. It ended up being a small wire in a wring harness that got crushed under the cab. The air suspended cab went flat and damaged wire harness.
The tech that worked on it put a $5,000 controller on it and didn’t fix it. So then we started looking at wires and found a broken one. They took the new controller off and she worked perfectly.
I also replaced the pressure sensors in mine, but they were only a few hundred bucks and pretty easy to swap out.

Have searched for broken wires. The way it started was it was working fine one day then the next day it started not shift about 45 minutes started working again. Did the same thing the next day. Then after a few more days finally just stays on d range and rabbit. The dash pressure light sometimes comes on. Changed the filters but still not working. Tech hasn’t ever got back to me. Going to have to figure this out on my own looks like.
