Dawg,
I understand your patience running out and, concern over what is the next shoe that drops, repair-wise.

No idea of your financial situ/needs, but here's my 25Cts: it's normal to
get to a point with a car where one sez, "I'll toss the sumbitch and get
a new one". Normal...my only admonition is even a few grand a year,
the car one owns is the least expensive car available. If you want/need/
gotta have a new ride, well there are a couple dozen rationales, all of
which make sense.

It's your pick, but I agree with V on the trans fix...and, JCL's comment
is right up there in RackIt territory, imo.
Good luck with whatever car situ you decide on...
