Check transmission light on and cannot change gear it only stuck on fifth? Error code p1c9d?

I want to ask if 2-4 gear sensor position is bad why it work normally and error after 100 km move?

I want make try to disconnect all cable from the hydraulic shift actuator clean it and connect again may be it fix the error

What do you think?

Is gear shift position sensor inside valve body on the conductor plate?

The mechanic asked me if I changed the release bearing before, I said yes because there was a leak, then he asked me if I replaced original new I told him I'm not sure if it was original or not. So, he told me maybe it's not work good and sometimes stuck and appear error code.
(Mechanical out of range on 2nd-4th actuator)
P1D74
And p1c9d (2nd-4th gear sensor position signal incorrect)

What is your opinion bro?

My mechanic found that the old mechanic who worked in it before making big problems by adding glue material to hold the bearing he decided to rebuild it again.

He replaced the k1 bearing and this long shaft inside the transmission because the stupid mechanic before put some glue and internal oil seal damaged and there is some oil on the clutch, he told me he thinks after rebuilding the transmission everything will be good and valve body will not need replacing.

Test today good he sent to me video but I told him try to drive like 1 hour then take rest 30 mins and turn on the car again check if still there p1c9d or not. He told me also the clutch not 100% good but its 60% because there was internal oil leak but no problem we can replace it later.

He told me since 1 hour it appear 2-4 gear sensor position so valve body must be replaced.
:(
What's your opinion?

I think I will go to dealer because all outside mechanics I can't trust them.

I think its transmission range sensor.

We tried another valve body it was for fiat x500 car move normally but check transmission light on again, but gear still move normally up and down shift normally

In old valve body when check transmission light on gear go to limp mode that is the different.

In two valves case the same code : p1c9d-00

The mechanic told me he will try valve body for renegade tomorrow, and he also told me there is short cut he tries to find so he need time to get it.

Note : he checked other sensors all work good.

Replaced valve body and drive 120 km back to home everything good and test today 50 km was good. Also,
Valve body with warranty 3 months.

Same problem today bro, I drove for 30 minutes inside my city suddenly check transmission and start/stop light on also, but when I accelerated car does not respond to move, then I turned it off rest 30 minutes with take off battery cable(-) then I drove it home.

I talked to someone he told me u have electric problem in the wiring harness

What can I do?

I talked to the mechanic who replaced the valve body, he said try to go home and he will tell me to disconnect (start/stop sensor) he thinks the problem from it.

What do you think?
