Hello, Scotty; I have a 1986 Toyota PU with a manual transmission and carb'd 22R. The engine was recently professionally re-built with OEM parts and the truck is in overall good mechanical condition. I plan to keep this as a daily driver for many more years. My current problem is that I have had two trustworthy mechanics tell me that the transmission will not last much longer, although neither has said exactly what is wrong with it. I have three questions if you would please help with some advice. First, do you know of a reputable manual transmission re-builder for this truck? I have searched online but have not found one that rebuilds Toyota manual transmissions. Two, is there any sense in draining the transmission fluid, adding new and trying some type of silicone or other lubricant to see if it quiets the transmission? (I doubt this will work but had to ask.) Third, the late 80s carbs seem to be difficult to tune compared to older carbs and fuel injection. I was thinking of upgrading to an aftermarket EFI system. I have seen a few that bolt on in place of the carb and then require an O2 sensor, high pressure fuel pump and fuel return lines. Have you had any experience with this type of system? What is your opinion on doing this upgrade? Are you able to recommend a brand name? Thank you very much for your help.

How many miles? My first car was a 22R carbureted Toyota pickup extracab.
