I put a new Vac diaphrm in my ranger because of eratic shifting and no gear
response at all at first starting - once it warms up it does better, but
still slips occassionally and was getting worse. The trans is pretty new -
4/2003, but less than 15k - (A rebuilt), but warranty is 6 months past. The
ownners manual suggested repalcing the vac dia in the trouble shooting
section at the front of the book. The symptoms sounded like what they
described...

The old diaphram had a pin inserted in the tube which mounts into the
trans housing, but the new diaphram I bought did not come with one - was
it lost, did it not belong there in the first place??? The pin looked like
a thick piece of pencil lead about an inch in length. I lost it, anyway,
but still put the new diaphram in without a pin -- Still having problems
with the gears, but behavior is different.

Also, There is a screw that can be adjusted on the outside face of the
diaphram - What does turning the screw in vs out accomplish relating to
the performance of the part????

HELP!!!!

without the pin you don`t have a functioning vac dia. "Find it" KB

Without the pin, the modulator that you installed won't do anything. A
transmission shop will get you one (probably for free).
Sadly, I suspect that there is more to your transmission than a defective
modulator or adjusting the one you bought. The symptoms sound more serious
than that. And it's not unusual for rebuilt transmissions to fail. There are
rebuilds and there are rebuilds. The better ones cost more and come with
long warranties. If you don't trust the place that rebuilt your
transmission, go somewhere else, but a chat with a good transmission
mechanic is in order.
