Depends on overall condition and any rust?
What sending unit is wrong?
IMO a daily driver condition eagle with current inspection minimum price is $1500. If the trans is in need of rebuild 1,000.
Running operational parts car $600.
If its in nicer shape and only needs a transmission to take it to a cruise in night $2,000.
If show worthy with low miles you could push for $4K being a rare Kammback, although (IMO) arent as neat as an SX/4.
(U will sit on it for a while at 4K depending what it needs)
A local mopar shop can rebuilt that trans and be out the door for about 1,000. Thats still a cheap car.
my wifes chev. Cruze trans cost us 3K+
