I have a 3 sync overdrive transmission, that I would like to test out. I was going to put it in a 65 MGB but sold it. Now I'm thinking about putting it in my 1600 MGA or selling it, but would like to make sure it is operating properly. I have a junk 1973 MGB with the 18V motor that Im using to test transmissions, ( cross member is cut out)
The input (first motion ) shaft appears to have the same splines and size but the older 3 sync shaft is about 1/2 inch longer overall, I'm afraid this will bottom out in the crank? The 3 sync trans is 5/8 of an inch shorter overall then the OD 4 sync
that came out of the 73 B.
There is also a difference on the bell housing starter bolts.
CAN A OLDER STYLE 3 SYNC OD TRANSMISSION BOLT UP TO A 18 v MOTOR?
I 'm not trying to test the units on the road, but have the car jacked up spinning the tires. So question #2 is could this present a problem testing out the Sync's downshifting? I wouldn't think so being the driveshaft is still turning when I downshift.
Thanks for your input.....
