will TCCM affect the park brake not disengaging with accelerator? I have to manually disengage it.

There is a connection at the transfer case on transmission correct? Possibly bad connection here?

Another thing I notice is I am not restricted with speed even though it is stuck in low.

I want to check everything possible before getting a new TCCM.

Does anyone have the electrical library for the 2005 lr3?

i have found 1 wire on passenger side that I do not know what it hooks to.

Broken wire passenger side “A” post. Appears that this light brown wire goes towards the driver side in the wire bundle above
Based on length, looks like the wire hooks up to this connection.

I am thinking these 2 codes are causing my issue. Any suggestions where/what to look for or test?

I appreciate your input.

i should have opened the TCCM when I saw corrosion on pins...looks to have shorted out.

All my trouble shooting is not wasted...at least all connections are cleaned with electrical contact cleaner and I used dielectric grease on all connections.

From what I have read a new TCCM needs to be programmed correct?
