Hey guys, I have a 1990 Ford ranger 4.0 5 speed 4x4. I bought the truck for $200 and I drove it for a day and found out the transmission had a whole in the side of it. Long story short I did a manual swap with a fm146 out of a 89 ranger 2.9. It was a pretty straightforward swap, direct bolt in. And for a transmission that cant hold up to a 4.0 it lasted about a year and a half, I wasn't very easy on it lol. I was lucky enough to find a M5od-r1hd in a junk yard out of a 01 ranger fx4(with the boss for a manual shift tcase). I got it rebuilt and swapped it into my truck it was also pretty straightforward too. Bolted right in.
Anyways.... ever since I 5 speed swapped the truck it has idled at 1,500rpms and I cant figure out why. I couldn't find any vaccum leaks anywhere and also cleaned the throttle body. But haven't changed the ecm. Is there a difference between the auto and manual ECM's on the older rangers? And if I got a manual ecm would I have to get it programmed for my truck?
