My 1991 Dodge Ramcharger, 5.2L, (318) V8, auto trans,. I have had this
truck since it was built. I special ordered it and picked it up with 7
miles on it. I have taken great care of it, getting it lubed and
changing all the fluids on a regular basis. Granted, my truck has
126000 miles, but it has always been very reliable and dependable, but
lately it has started to shift hard and at high speeds. When
increasing speeds, it shifts out of first as late as 20mph on the
speedometer (don't know specific RPM), and the same reading when
decreasing. It shifts into second around 30mph, third at 40mph and
then fourth at 43mph. I have not really felt it kick into 5th
(overdrive) lately. In addition, when braking, it also tends to
downshift hard and when coming to a stop, just as I am about to be
completely stopped, the truck downshifts and LURCHES right at the end
of my stopping period.
The worst thing of all is how hard it is shifting. It bothers me that
it may be seriously hurting my truck.

I may have a bad TPS, not sure if that can affect it, but I am planning
on changing it to see if that helps or hurts. Also, my cruise control
is tango uniform (TU) these days. Been a while since I used it, so I
don't really know how long it has been inoperable. My engine codes
say I have a short in the speed control, and again, I am not sure if
that can cause any or all.

Please advise.

Thanks

I do have a code that says my torquer clutch selonoid is either open or
shorted.

Could that be the problem, and if it is, where is it located?

My trouble codes are:

12
35
37
51

Actually, this is what my truck is doing:

91 Dodge Ramcharger shifting irregularities

I have a 1991 Dodge Ramcharger, 5.2L, (318) V8, 4 Speed (O.D.) AMT. I
have had this truck since it was built. I special ordered it and
picked it up with 7 miles on it. I have taken great care of it,
getting it lubed and changing all the fluids on a regular basis.
Granted, my truck has 126000 miles, but it has always been very
reliable and dependable, but lately it has started to shift hard.

When increasing speed gradually, it shifts out of first at ~23mph on
the speedometer (don't know specific RPM), and roughly the same reading
when decreasing (~25mph). It shifts into third at ~40mph and then
fourth (O.D.) at ~43mph. It does not shift as hard when I increase
speed rapidly, and it shifts into 4th at a relatively higher speed
(~50-60mph) depending on how fast I am accelerating. In addition, when
braking, it intermittently downshifts hard and when coming to a stop,
just as I am about to be completely stopped, the truck LURCHES
backwards, more like it settles very hard) right at the end of my
stopping period.

The worst thing of all is how hard it is shifting. It bothers me that
it may be seriously hurting my truck.

I may have a bad Torque Clutch Selonoid, not sure if that can affect
it, but I am planning on changing it to see if that helps or hurts.
Also, my cruise control is tango uniform (TU) these days. Been a while
since I used it, so I don't really know how long it has been
