Both buttons light up at the same time. But it stays in 4HI. The 4LOW Lock is just on as well. I am due for a fluid change in the t-case. I will do that and pull the speed sensor to clean it up as well.

I know this may sound stupid but..... Have you tried disconnecting the battery (both pos and neg) and touching the leads together. This little trick sometimes corrects little "burps" in the PCM and BCM. Only a few minutes of your time, free and it just might.help.

Sorry it took so long to respond.
I did try the battery trick and no luck. What i ended up doing was draining the t-case and pulling the speed sensor and cleaning it. Then pulling the shift motor and cleaning it up and flushing the t-case a bit with some fresh fluid and filled it back up. It stayed on for a day more. But the next day the light went off and has not come back on. Not sure if all that work was the solution or if there may be a faulty sensor somewhere... |
