Shifting Problems

I've got a 94 S-10ext. cab w/push button shift on the fly 4x4. When I'm driving down the road the 4hi light will come on w/out any reason. When I push the 2hi button for it to go off smoetimes it'll shift into 4lo which is not good. What can I do is the switch or the control module or the eletric shift motor? Help this is not good for the T-case.

Hey I really don't have much expierence with the shift on the fly, however I would first check all the connections at the T-case and then behind the shifter button thingy, the shift motor might not be a bad start either, when it shift to 4low does it actually engage at highway speeds? just wondering. good luck.

If it has tits or tires it will give you trouble.

Re: Shifting Problems

<font face="Comic Sans MS">4 lo @ 50mph, didn't that send your RPM's right up to the redline (or past it) also? [img]/wwwthreads_images/icons/crazy.gif[/img] I'm not sure how to fix it but my guess is that you'll need a new (or at least rebuilt) t-case after that incident. Did you pull the drain plug on the t-case to determine how many links of chain or scraps of metal decide to pour out? Is it still drivable currently? Sounds like something is messed up inside the switch itself if it's sending power to engage low range (although I'll admit I don't know much about electronic shifted cases...).

Re: Shifting Problems

That doesn't make any sense! It was probably cool when it happened, but it sucks after, that's fer sure!

First off, your push button isn't supposed to let you shift into 4x4 LO without the clutch (or neutral on autos, I'm pretty sure), and over 2 mph. That's telling me that there is a short in your clutch switch or whatever the hell the module is that controls it.

Everything on a pushbutton system should point to the module, or the wires connected to it.

I had a F8rD once that had the first of its generation in push button 4x4. Sometimes it wouldn't work unless I opened the DOOR on the driver's side to hit the switch. Sometimes the switch on the clutch went bad. Then it finally gave up the ghost and literally burned up while I was driving. Had to swap in a manual shift Tx-Case after that... Good thing it rolled and I had to get rid of it!

Anyway, to reiterate, check the module!

Re: Shifting Problems

a lot of thngs had to go wrong all at the same time for that to happen, nutral switch- does your truck start iun gear?, can you put it in 4 lo yourself over 5 mph(do go anyfaster it might fall off) if these happen have the module checked... if its good your trucks brainbox is dead or dying... the strppermotor in the t-case wouldn't judt start working for the hell of it.. although you might want to check the overall tightness of things down there...
