I have a 1991 Spirit 2.5l auto 3 speed, has 275,000 kms and runs well.
Lately I have been having problems with the tranny.  When I come to a
complete stop and then go again it feels like I have a caliper seized, the
car needs quite a bit of gas to get going again.  Once underway it feels
like something lets go and it is ok again.  I have been trying different
things and have found that:

1.  If I don't come to a complete stop, it happens less         often.
2.  If I let go of the brakes at a stop it feels like I am held       there.
3.  If I let go of the brakes and shift up to N and back to     D, there is
no problem.
4.  If I hold the brakes hard and shift to N and back to D,     there is no
problem either.

So I think that I have ruled out the seized caliper, but don't really know
what to do next.  I have had the car stay in first gear for a while when
cold once also.  I have not had the fluid changed since I got the car at
252, 000 Kms, going on the assumption that it may be bad to change the fluid
at that mileage if it has never been changed before.  I will change the
fluid asap but will wait for feedback first.  Any help will be appreciated,

Dave.
