Hello everyone I'm new here and new to volvos I have a 1989 Volvo 240 wagon. It is automatic at the moment I was at the junkyard and I found at 88 with a 5-speed and I'm going to take the transmission the clutch the flywheel the clutch cable the only thing I can't get from there is the clutch pedal and the drive shaft. Is there anybody that could clarify would my automatic transmission two-piece drive shaft work? They are both the same exact car except one year off. Could probably put a mustang clutch pedal in because they both use a cable don't know just yet I just want to swap to a 5-speed I'm not in automatic kind of guy and these are getting very rare and hard to find any help would greatly be appreciated
The driveshaft for a m47 does not use 3 traditional ujoints like the automatic - the front joint is a flexible disk.
You should get the Volvo clutch AND brake pedal - a used parts place like Voluparts in Atlanta might have one - 404 352- 3402. If your car has a flywheel speed sensor for the fuel injection system - make sure the 88 does also - I don't remember when that change was made on the 240. An easy way to tell is - the ignition distributor - if there's only a rotor button inside the distributor - there has to be a flywheel speed sensor and that picks up a signal from the flexplate with an auto OR the flywheel with a manual.

Here'shere's the problem what do I do about the driveshaft though because the car doesn't have one. do I get one made or is there a way that I can just buy the front half of it for my existing one and put that rubber disc on or what exactly can I do?
driveshafts are balanced as a unit, you can't just mix and match halves. further, a manual 240 might have either a M47 5-speed, or a M46 4-speed plus overdrive, these use different length driveshafts, so you need the one thats matched to the transmission type.
and what hoonk was saying about the timing, your 1989 uses LH2.4 injection and has a crank position sensor on the 'flexdisk' (equiv of a flywheel on an automatic car). a 1988 has the older LH 2.2 injection, and thise used a timing ring inside the distributor, with a hall sensor. you will need the flywheel from a 1989+ 240/740/940 (1990+ if its a turbo 740/940).
that 1988 automatic transmission, the bell housing won't have the notch it needs for that crank position sensor, AND the flywheel wont have the timing notches.

So so what you're saying is is I cannot use that transmission? And my car has a b230f

can I just notch the top of the bellhousing? And then just buy a different flywheel and clutch kit? And then just get a one-piece driveshaft made?
a 1 piece driveshaft will not work, it has U joints for a reason. the differential/rear axle moves up and down with the rear suspension, the drive shaft has U joints in the middle and rear that stay approximately parallel when the differential goes up and down, also has a spline in the middle that slips in and out to compensate for the different radiuses at different rear suspension positions. the U joints stay parallel to cancel any 'cogging' vibration at speed. the flex disc in the front is to allow the engine/transmission asembly to move slightly on the motor mounts and isolate any driveshaft vibration from those moves.
Sure the speed sensor is bolted to the engine block,
Yes the correct flywheel will be needed, either a flat one or a stepped one.
No- you need the correct driveshaft.
honestly though to be fully truthful pick up trucks use a one-piece drive shaft so why couldn't a wagon? And all these people that swap in LS motors and two Jay z's and whatnot they all use a one-piece drive shaft as well
The M47 transmission (pure 5 speed) has a flexible coupling on the output flange of the transmission, a center ujoint and a rear ujoint. That flexible coupling is not designed to flex up and down. The engine swaps you are referring to might have 1 piece driveshafts - but they have a ujoint on each end and still need a sliding section.
You could source a M46 Volvo manual transmission with the electric laycock overdrive unit on it - but that requires wiring and a relay and the overdrive unit at this age is probably bad. The driveshaft for that transmission looks like the one for your automatic with 3 ujoints.
