I'm getting 2 error codes on my 03 chrysler town & country, P0700 and P0605. according to the mechanic its the P0605 that put my car on limp mode and the TCM needs to be replaced. I just want to get a second opinion if its really it or are there other possibilities that's causing these errors. Thanks...

no, before doing this, take it to a trans shop to verify. it could be a wiring issue for the 605. the 700 is a generic internal trans issue.

you may have more than one issue here.

the harness under the battery tray is a constant failure from a leaking battery. check the integrity of the harness before going to the tcm.

I had it checked and there's no visible signs of corrosion or damage to the harness up to the TCM. I don't know if it's good news to know but it made me sweat :( what else can I do ? !?

get a shop to check it for you. it most likely will have to come out and be rebuilt

A few days ago my power door locks stopped working on top of my P0605 problem, just what you suggested I brought in it and the car electrician checked the wiring harness, fuse box and ground connections. And found out that the iod fuse is grounded and causing to drawn power to the battery, the guy can't seem to figure out how to resolve the power door locks issue.
I just don't know where to start now ....

one thing at a time. have him repair the fuse issue and move forward. electrical issues are tim consuming. give him the time to do it correctly.

For the case of the malfunctioning power door locks what seems to be causing it? Can it be a faulty actuator? If its an actuator do I have to let all 4 doors check?
The remote still works in opening the side doors and it can still arm and disarm with the horn still honk to arm it, it but the locking system does not follow.
All the accesories running under the iod fuse they made a visible inspection for possible shortage or lights left on, no problem there.
Thanks for your patience...
