Is it electrical?

Asked by papatruck Oct 20, 2015 at 11:39 AM about the 1994 Chevrolet S-10

Question type: Maintenance & Repair

OK so about a month ago I had to replace a
water pump after it went out.  After fixing it,
and diving home I noticed I cracked
transmission to radiator line.  It was bad
enough that on the way home it went into
fail safe mode.  I fixed that.  But now the
speedometer will sometime act weird.  It
will jump around, stop reading or say I'm
going way too fast for what it feels like I'm
going.  It will then run rough after about 30
minutes of driving while the speedo is
doing this.  And before that the
transmission will go into fail safe mode.

If it does this the battery is dead even if I
get to where I'm going an shut it off.  Once I
jump it.  It will drive fine for a few days.  
Sometimes longer than others.  I notice
when it did it this time there was a lot of
moisture in the air this morning.  Usually I'll
be able to get to work before it's done.  
Today I had to tow it home.

Anyways.  Is this electrical?  Did I nick a
wire some where and it shorting out?  I've
replaced the battery.  The alternator works.
The ccheck engine light will come on and
off.  Sometimes it will stay off.  I have no
clue where to look for the problem.  

It has a new fuel filter.  Not even a year old.

It's a 4.3 TBI, 2wd.  If that helps.  Any ideas
would be great.

The trans doesn't go into fail safe mode (stays in 3rd gear) for a bad cooler line causing low fluid. It's gonna be something electrical. Just to make sure, what is it doing in "fail safe" mode?

Well it usually does it after I've driven it for about 15-20 minutes. Before that it will drive like it has no problems what so ever. Then the speedometer will bounce around regardless of the speed I'm doing. When it does stay in 3rd gear. It stays in it even if I stop at a red light. I've been told the 4L60E uses a speed sensor for shifting. But it's not all the time. I could jump it, and it will drive fine for a day or more. Then it will act up. I've noticed if there is a lot of dew on my truck in the morning it will act up.
