Drive Train / Driveline Malfunction When driving Always
Q: dfs I have 1996 Chevrolet Tahoe and it has an electronic transfer case. The vehicle will switch into four low via the inside electrical button and back out of four low. It will not switch into four high at all. The indicator lights also do not light up when the vehicle is in 2hi or 4hi but I can tell that it has switched out of four low by the driving characteristics. Any suggestions?? I was trying to avoid a costly dealer fix. Thanks
Q: How do I disable/disengage the "governer" that stops the vehicle from exceeding 100MPH.?
Is there a simple way to do this?
A: The "governer" as you put it is in the software installed in the vehicle computer.
This was installed as a safety feature so not to exceed the maximum safe speed of your tires.
There are programming kits you can purchase from performance shops and catalogs.

Q: Sometimes when starting, the speedometer, tach gauges don't register any readings. Also it shows no shift indicator light for the automatic transmission (p-r-n-d-l).
Then putting it into drive, I have one forward gear and it won't shift. Other than the one forward gear, I only have reverse.
This only happens every so often and it works and shifts fine most of the time.
What do you think?
A: Hopefully a poor ground problem....
Run 10 gauge wire connections from the negative battery connection to the engine block, and from the metal body panel behind the engine to a metal part of the engine.....
If no improvement, I think you may have a controller (computer) problem.... Ed
Q: When I am driving, I get like something is rubbing when I hit a small bump or dip in the road.
I recently installed flow master mufflers with dual stainless steel tips, exiting each side of vehicle behind the wheel. I recently put four heavy duty shocks on also.
Could this possibly be the exhaust or the shocks?
A: Check the exhaust clearance first..... sounds like it.... Ed

Q: Hi John.
I've heard it said that I shouldn't tow this truck behind my motor home.... perhaps a simple question.
It is a standard shift, 2 whl drive, so what else is needed other than to put it in neutral, and turn the key to the first detent?
A: Transmission is still connected to the driveshaft . This could pose a problem . Keeping it in neutral ony protects the engine . If towing from the front , leave the key out since allowint the steering wheel to turn is no longer an issue . Disconnecting the driveshaft from the transmission might be a bit cumbersome , but it removes any issues with the transmission . Make sue that the driveshaft is securely tied so that it can not come loose and strike the pavement . You might want to consider a trailer for the truck and avoid any problems all together .
