My 1982 Volvo 240 D24 Overdrive needs to be swapped with the overdrive from my 1984 240 D24.
I am wondering if these are interchangeable...
Similarities:
1. Both cars are the D24 Diesel.
2. Both cars have the same "K" number on the dash cluster
(the '82 goes to 85mph, where as the '84 goes to 120mph)
3. Both cars connect to the overdrive via the speedometer cable on the side of the OD
4. Both cars are the M46 transmission.
5. Both overdrives feature the smaller speedometer gear that inserts into the side of the OD, connecting to the cable.
Differences:
1. The Overdrive on the 1982 features an additional speedometer gear on the annulus, where as the 1984 does not have the additional annulus speedometer gear (see photo)
2. The '84 has the "later" relief-valve design.
Are these overdrives interchangeable as-is?
How exactly does the '84 determine speed without the larger, annulus gear?
