Will a 1988 Volvo 4 cyl. motor from an automatic tranny car swap with a 1988 Volvo 4 cyl station wagon that is identical, only with a manual transmission? As far as I can see, the motors are identical, but I don't want to buy it and find out it won't mate with my manual tranny.

It may not fit!!
Virtually all standard transmission clutches need a pilot bearing installed in the rear of the engine's crankshaft.
Automatics do NOT need pilot bearings.
Almost all american manufacturers and many import makers do NOT bother to drill the hole required for a pilot bearing if the engineis going into an auto trans car.
Maybe Volvo does, maybe not. If you can, pull your old engine and compare the back of the crankshaft with the auto trans engine. If everything looks the same, go for the swap. Otherwise, stay away.

MagicRat is correct in his statements. I would suggest going to the dealer, sometimes the autopart stores can help, and ask them for the part # of the crankshaft on each engine. They should have different part numbers. Also, don't forget to replace the bell housing. An auto trans is different from a manual (don't forget all the parts for the manual need to fit inside the bell housing.) Lastly, make sure the mounts are the same for both transmissions. Some cars have different trans mounts depending on auto or manual due to transmission length etc that changes the driveshaft angle. To sum up, research the part numbers and asking a Volvo tech (Ford, yes Ford owns Volvo) should help.
