Fresh 5R110 Tranny issue

[Biggsw784]

Just had my tranny rebuilt with a rcd converter and suncoast ironpack 3 rebuild kit and after getting it back it is acting wierd into reverse. Once I put it in reverse, I have to barely hit the throttle for it to engage. Now once it goes it is perfect. Now 1st gear is doing it only sometimes though. I am thinking it is the solenoid that controls the low/reverse since they are on the same circuit. I was told that the location on that solenoid was on the back row on the drivers side?? Has anyone seen or heard of this issue before?? Thanks for any info.

definitly could be a solenoid issue ,is there by chance any codes popping up

NO codes man

I actually just drove it again and it did throw a code this time. Actually 2. P0766 and P2703. It has gotten worse.

Did you figure out the problem you were having? I just recently had my 07 5r110 rebuilt and it chatters when I put it in reverse. After it engages its fine. I dont have any codes either.
