No

I would drop the pan and check for debris sounds like the primary clutch or the chain is failing

I dropped it and didn't find any metal shavings just a very small amount of clutch material... It shifts to all gears but while driving it won't shift from first gear
Automotive Expert
it shifts from all gears when?

From P,R,N,D... it goes into them gears ok... just while in Drive it won't shift from 1st to 2nd gear..
Automotive Expert
ok could be a valve body issue a stepper motor issue or a primary and secondary clutch issue..Line pressure needs to be checked next.. it could be a valve body failure but thats almost as much as a reman cvt..Usually wiser to replace the cvt at that stage

Would it be possible that I should get a check engine of some sort if the valve body had problems...
Automotive Expert
it would be ideal but not always..Have you scanned for faults or just assume there are none since the light is off?

I actually scanned them and it says no DTS's present. I actually replaced the stepper motor all so..Which one will you chose next between the TCM or input and output speed sensors
Automotive Expert
can you monitor input and out put speeds on your scanner? if you can that would prove or eliminate that thought

I'm not sure. Do u know what the abbreviation would be on the Scan Tool

oss tss vss maybe

To check the gear oil level (https://www.yourmechanic.com/article/how-to-check-your-engine-oil) on your vehicle, there is a filler plug located on the drivers side, front of the transmission. The oil level should be 0-5mm below the lip of the plug hole. Keep in mind...
When replacing the harmonic balancer do I need to or is it recommended to replace the crankshaft seal or anything else with it
