Howdi. New to the forum and im stuck. I bought a 2011 compass with not selecting “gears” issue. Found the was an leak on the sump bolts very loose. So removed its drained fluid and done the following.
Replaced sump filter and cooling filter. And sump gasket torgue to spec and refilled with triple q cvt fluid done this as per jatco instructions drove it to mot x2 and to work it would not change up stuck in low. Fault codes p0777 and p0730. Would not clear. Checked fluid all ok unplugged and refitted all elect connections still same so drained and pulled valve body and also checked belt very clean inside and belt ok. Stripped valve body and checked all solenoids operational cleaned everything and refitted refilled. P0777 gone but p0730 stay pulled speed sensors and replaced output sensor intermittent reading in scanner
Have done a initialisation and cleared errors but comes back p0730

. . . it is crazy expensive even in junk yards . . .
And who knows what you're getting? I strongly suggest you not go for a junkyard transmission unless it has less than 50,000 miles on it. CVT fluid & both filters should be changed at least every 50,000 miles, some say sooner. Since most owners follow the maintenance schedule in the owners manual, yanking a CVT from a vehicle with 100,000 miles on it is getting one that is doomed to fail sooner than later. I think you'd be wiser to get a factory rebuilt, or if you have a tranny shop you trust, have them rebuild the one you've got.
