Background-
I picked up a recovered theft Typhoon at auction last fall, and found the truck to be in better shape than
the auction house listed it. They said it had a bad engine, but it was just a loose power steering bracket
making noise. I found most vacuum lines in sad shape and mis-connected. Some minor wiring issues,
the worst being the stereo. The only 'major' mechanical issues found were missing front drive shaft and
a fuel pump that had was not functioning properly.
I work from home and was able to address all of these issue without putting many miles on it, and after
fixing everything I found I prompted it to my daily driver. At which point I found one more issue, cruise
control was not working and the ABS light would turn on at 15 mph and back off if I dropped below that
speed. Research revealed that would likely be a vacuum release/TCC brake switch. I did not have one,
but digging around under the dash I found what was left of one. I found only ONE new unit anywhere in
the country and the seller wanted $300 for it. We negotiated and I finally only paid $45 for the $12 part,
but at least now I had one. Cruise still did not work, but the TCC did and no more ABS light.
That was two weeks ago. Last night while pulling away from a stop sign and approaching 35 MPH
the engine revved up and the transmission acted like it was in neutral. I pulled over the tried each
gear manually, including reverse. The truck will not move under it's own power in any gear, forward
or reverse. I did not lose a driveshaft or a transmission fluid line. The fluid level is in the normal range,
and is not burnt.
I wrote this novel to provide as much info to help narrow the problem down. I am not sure if the t-case can
fail in a manner to prevent any power being transferred. Note that in park the vehicle cannot be moved, which
I think means the t-case is not the problem, but I may be misinterpreting that detail. I suspect an easy fix
is not in my future, so I'd appreciate any guidance this group may have to offer.
