The actual part price was $350 CDN and the rest was shipping and handling. The price for a new tranny, which is probably a reman, is $3100 USD not including shipping. The salvage yards I contacted won't just sell the solenoid either. I found a tranny in Thunder Bay for $200 CDN that would probably cost another $150 to ship. Either way replacing the thing would have been a costly venture in Canada. There are a lot more trannys in the US. Car-part .com has 3 full pages of listings there. Up here there are only 4 trannys listed. I think the A500 you listed claych is a Chrysler tranny. When I received the first solenoid I ordered from Carquest they sent me a solenoid for an A500. I didn't think these trucks had 2 different trannys in the same model year.
Yessir, Pioneer Transmission is #1 in my book. They've been around a very long time and their bays are always full.
