My 96 S10 has an occasional P1870 after HWY use when its hot.
Researching this brings up a lot of reference of the TC slipping due
to valve body wear. It seems a lot of people rebuild the trannie
before ever trying to fix the valve body. A couple of companies make
a kit to do this repair:
Can the valve body be taken off a S10 with the trannie still in the
truck by dropping the pan? Does it take any special tools to get
the valve body off?. Is a driveway valve body repair/swap feasible?
There is a special reamer to enlarge the valve body bore to install the
steel sleeve correcting the wear problem. This can be a challenging job
without having some sort of prior trans repair experience, also.
Yes i saw that. The reamer cost more than the part.
Does the reamer have to be in something like a milling machine,
or can it be used with a hand drill?
This can be a challenging job
The reaming part of it or the valve body R/R part of it?
There is a guy on ebay selling the rebuilt body's for $250 or so.
What i am trying to figure out is if you drop the pan, drop the filter,
and then the valve body just unbolts? Any special tools?
Lots of stuff connected to the valve body, it should come out to do it
properly, the reamer is a hand tool that is self guiding into the bore, This
should not be that expensive to have done, most trans shops have lots of
experience with this, get an estimate and decide.
