TCCM Problems

I have a 2000 Blaber LT 4x4. I am havingproblems with what feels like poor acceleration and 4x4 problems also. Went into 4lo and won't come out. Just today it threw a code. P1875 which I think is the TCCM since I've been hearing a clicking noise under the dash. I mainly just want the truck to run well in 2hi. Can I simply unhook the power going in or coming out of the TCCM if I don't plan on using the 4WD? Would that affect anything else?

Re: TCCM Problems

You have two problems.
Check engine running and tune up end for not running right.

The 1875 code is for 4W low switch circuit or switching problem.
Any other codes?
Try a battery disconnect and see if it will shift back to 2W drive.
