I have an '88 toyota pickup 4x4 with the 3.0 v6 and a 5 manual trans. Transmission is shot, no 1st or 2nd gear. I'v got a great deal on a trany from an '89 pickup. Local trans shop and dealer are telling me that they are not compatable. What is the diff. between the '88 r150 tran and the '89? Will it work, if so what mods do i need to make, or is there a better year that will work? Local trany shop has quoted m $1700 to rebuild my old trany, only if they don't have to replace any gears.
