Any help with y66/1-104,08-no start, limp mode
 

Hello everyone-I'm in need of help with this transmission code listed above. There is no start when I turn the key. Car can be started from fuse box and drive in limp mode. These codes were pulled from iCarsoft MBII. Thanks in advance!!

check the tcu located in the engine compartment fuse box for fluid leakage

if fluid is found , clean the tcu then replace the conductor plate and electrical connector on the transmission to prevent more fluid from leaking and damaging the tcu again

Attachment 360644

Thanks bro...did that. No trans residue. Did notice a lil bit of green residue like possible water. Pulled out TCU cleaned with electric cleaner; still a no go.

Is y66/1 lock solenoid located on the conductor plate or the actual shifter?

Any solutions to y66/1 solenoid trouble code?

In need of help
 

Where is the y66/1 r/p solenoid located? I'm getting DTC 104 and 008. Anything over 96 is a stored code; which leaves me 008 r/p lock solenoid. No start, can jump from relay box, limp mode. I have changed the conductor plate-no change.

A 30-second search on Google shows that the Y66/1 solenoid is the one in the shifter that moves the shift lever locking arm.
