98 Intrepid trnasmission problem

My transmission wont shift up and speedometer shows zero. What I found in
the internet, tells me that output and input sensor should be replaced. Some
mechanic run my car thru the computer and told me that some transmission
computer needs to be replaced too. Is it possible that at the same time all
these parts could be broken? It looks to me kind a illogical.
thanks

Thanks for a very good link, but it doesn't answer my question entirely.
Anyone know more about my problem?

 

Fix the speedometer problem and your transmission will more than likely also
be fixed.

If the speedometer in reading zero, then it is most likely the output (drive
shaft) speed sensor. The part cost me about $25 a few years back. IIRC,
the part number was the same for my Eagle Vision and the T&C Minivan as
well. (I've replaced them on both as they are a common failure so dealers
keep lots in stock). The replacement will take you about 5-10 minutes max
and is pretty accessible from below if you have a large wrench. It is a
cheap and easy fix. Make sure the connector is clean when you reconnect the
new sensor. Good luck.

I'll state it even more strongly: The input sensor being bad will not
cause the speedometer to not work. The output sensor being bad will
cause the speedometer not to work (as well as the stuck in second gear
thang). IOW - yes - replace the output speed sensor.

1" to be exact. Generally a regular 1" socket works - sometimes a 1"
open end works better on one of the sensors (I forget whether that's the
input or putput one) due to straight-on access of a socket and extension
not being very good.
