I ran through some brush,[a lot of it] after I got through the brush my truck would not shift out of low gear without running up the R.P.M.s. Even then it would not shift no higher than 2nd gear. I also have no speedometer.

The truck was fine before I ran through the brush. Did a limb run up into the framework and knock something loose? If so, What??

Thanx for your help and God bless.

Check for broken wires, pulled off connectors, and bent, damaged shift lever. All on the transmission.

You need to check the entireunderneath, but particularly where the electrical connectors plug in on the tranny itself, and the shift mechanism on the drivers side of the tranny.

I can't find the answer that told me to check for wires loose on the transfer case. But whichever one who gave me that answer, Thgank you. It was correct and the tranny is back to normal.

God Bless all of you, Jake.
