[doejomo]

but i have the code for the TCM i dont get why the code would come up if there is no tcm

[RIP]

What code are you seeing?

[doejomo]

i am getting a code 66 and some other ones but that is for the O2 sensor

Your MIL code 66 has two different meanings. If you connected a scanner and read the scanner code that correlates to the MIL code 66 you would get either a P1698 - "No CCD messages from TCM" or code P1695 - "No CCD messages from Body Control Module" (BCM). Your problem is probably associated with the BCM. Autozone will read scanner codes for free. What symptoms are you seeing?

The BCM controls many of the electrical functions of the van. Symptoms usually include erractic instruments, door locks, lighting, wipers etc. Sometimes it can keep the van from starting. The code doesn't mean you change the BCM right away. There can be several causes.

well then i know its the BCM cause i have all those problems with gauges lights wipers what is going on with the van just one day it just didnt shift right takes longer for it to shift and at 55 seems like it is running at very high rpms it use to shift into 3rd at 40 nice and easy now it doesnt till 50 or higher and seems like its running in like im kicking it down to pass

[doejomo]

would the BCM also affect the heat too like the heater control and maybe the door that lets in the cool air?
