No Speedo after Transmission Repair
Hello.
Well I finally got my 98 TJ back together the other night, after having
the transmission & transfer-case out and have no speedo now. I checked
the speedometer connection on the transfer-case, looks good, took it
off, put it back on.. Jiggled wires, nothing. I'm going to look at the
FSM tonight, look where those 3 wires go, and see that I have
continuity all the way through..
The O-Ring around the speedometer sensor was leaking pretty bad I found
out, and when I pulled the speedo-gear out, it was pretty dry in
there.. a SMALL little spot of ATF could be seen. So, I drained out all
the old fluid, and put new stuff in, so now the speedo gear is actually
being lubricated. (when I pulled it out after realizing it wasn't
working, the yellow gear had atf all over it. Teeth look fine.
Any ideas what might be the problem?
I assume it's related, but my engine stalled twice after I started
driving home from my friend's where we were working on the jeep. upon
Decel, I push in the clutch, and the RPM's just steadily drop slowly
until the engine's out. Could the lack of a speedometer confuse the
computer and let the engine stall? On my way into work this morning, it
happened pretty consistently.
Then the CHECK ENGINE light came on about a mile from my house. I don't
have access to a code-reader yet, so no word what that might be, but I
had a MIL for my "downstream o2 sensor" about a year and a half ago,
and it magically went away a day later, never to return.. so maybe
after knocking my exhaust around while doing all this work, the o2
sensor is finally crapping out on me..
Thanks,
-Dave

Re: No Speedo after Transmission Repair
You have some connection issues someplace would be my guess. Ground
wire off someplace? Did one of those small black wires that hook on to
a bolt near the rear passenger side of the block get broken? Those are
the computer harness grounds.
And yes, the stalling is directly related to no speedo input to the
computer.

Re: No Speedo after Transmission Repair
The speedo gear is on an eccentric, a round plate where the speedo-gear
shaft is off center. Speedo gears have different numbers of teeth to
calibrate the speedo reading as the tires and gear ratios change. If the
speedo gear was on a shaft in the center of the plate it was mounted to,
then the larger gears would not fit andthe smaller gearw would not mesh.
What you need to do is loosen the bolt that holds the speedo gear into the
tcase, and gently twist the speedo gear until it meshes with the gears
inside the tcase.
