Hey, I was just wondering if the transmission out of an 85 ranger 4cyl diesel is the right bolt pattern for a 2.3L 4cyl gas? I'm thinking of getting a ranger 4cyl and putting in a 4wd trans and tcase for the low ranger capability.
 
I'm not an expert at all, but I was looking for an answer to a similar question (want to replace my seized '84 V6 with a newer, more reliable engine) and found a page on this very site about engine swaps that says they all have the same bolt patten.


"Transmission compatibility is a consideration in this swap. Several transmissions were offered in the Ranger over the years. The one common factor is the engine to bellhousing bolt pattern which is identical for all years. The early model manual transmissions have a shorter input shaft with the pilot bearing in the flywheel, while the later years are longer with the bearing in the crankshaft. Of equal concern is the light duty design of the early model, which makes it more vulnerable to breakage. Newer model transmissions use a slave cylinder inside the bellhousing, so you'll need those components and the interconnecting tubing if you elect to swap one in."

Actually that's not entirely true. the 2.9/4L transmissions are all the same bolt pattern. as are all the transfer cases.
However, the 3L and 2.3L have completely different transmission housings with a different bolt pattern. I just can't seem to find anywhere which one the diesel had, or if it was a stand alone pattern.
 
The mitsubishi diesel trans is a bell specific mitsubishi fm 145, since this trans was never an option for the 2.3 gas, there is no bell for one, you need a 2.3 gas 4wd trans.
 
On top of the excellent feedback already given, while a diesel-mated manual transmission would no doubt have high-strength gears/components to handle the high torque of the diesel, the GEAR RATIOS would be all wrong (too "tall") for the higher-rev'ing gasoline engine... ALL WRONG, every gear, even REVerse.

Do yourself a favor, and get the high MPG diesel engine too! :icon_thumby:
