Considering buying a mid 80s ranger w the 2.0 in it. I have to look if it's a 4 speed or 5 speed, but can someone give me a range on what new transmissions for those would cost? The truck is 1k, lower miles but needs rebuilt trans. I'll give more info when I get it.

 

I assume manual trans?

It will be a Toyo Kogyo trans but could either be a 4 or 5 speed, used from '83-'87
Look at the Drivers Door sticker and find the Trans Code
X = 4 speed
5 = 5 speed

You would rebuild the transmission or do an exchange for one that is rebuilt.

You would need to call local transmission shops for pricing.
Here is a site that lists cost of rebuild kits, so you have a general idea of cost:
Ford Toyo Kogyo 4 & 5 sp Rebuild Kit Manual Transmission - Drivetrain

With that old of a transmission I would be leery of getting a used one without rebuilding it.
