Hi everyone.! I am having a problem with my 05 2500 8.1 Suburban. The service 4wd light comes and goes.When it is on the 4wd wont work. Sometimes the lights on the switch go out,change to red and goes in to 4hi or low..Well now recently it started lighting the 4 low light.
When it does that the tranny shifts like it is in 4 low. It shifts out of 1st really early and shifts out early on the rest also.
I was wondering if anybody else had seen this before?
I am thinking encoder...Cause maybe the encoder does not know its location...Or the Tccm for maybe telling it to do so..
Last night after work the low light was on and i slowed and put the tranny in neutral and it actually went into 4 low..I have checked the fluid and had to add about 1/4 of a quart.
Any ideas ? Thank you ! Scott
