Guys,



Will the FMX bolt to my Ford-o-matic bell housing and use the torque converter?



Are the splines the same as my water cooled Ford-O-Matic? I can get a rebuilt FMX for $500.

Didn't want to spend to much to add an AOD.



Is it worth doing?

Jim:

The trans will bolt up if you locate and drill the top two mounting holes in the transmission case.  You can use the bellhousing to locate the holes.  To use the original converter, you will have to put the FOM front pump on the FMX.  If your original trans has a 29 spline input shaft, you are all set.  If your original is 17 spline, you will either have to install the 17 spline shaft in the FMX (a complete teardown of both transmissions) or find a converter with the 29 spline turbine hub.  You can also use the FOM tailshaft and housing on the FMX and use the original driveshaft, mount, and speedo cable.  If you do this, watch the gasket match in the lower corner, the FMX gasket will not seal the FOM housing.  Either use the FOM gasket, or add a little piece of gasket material and some rtv sealer as required.

Thanks John,



Would the same factors hold true for a cruize-o-matic?

Some early Cruise O Matic's came behind Y-Blocks. If you find one of those they are ok. They look like a Ford O but have a Vacume modulator on them. Shifts are more vacume controlled. Chuck in NH

By the way Jim, check the article in the Tech area at:

Jim:

Most cruisomatics bolt in.  Only the input spline could be an issue.  Your water cooled FOM probably has the 29 spline shaft.  As Moonshadow said, you'll need a vacuum line to the modulator, as will the FMX.  Can you get a rebuilt Cruiso?  If so, they should be able to rebuild your FOM and you wouldn't have to change anything.

Where would be the best place to get the proper vac, The carb  or the back of the manifold? Thanks  Gerry

If you put your town and state in your signature

help might be closer than you think.

Gerry:

You need manifold vacuum, either directly off the manifold or a carb fitting that is below the throttle plates.

Is there a way to adjust the shift point of the FMX trans at full throttle? 

Flooring it from a start it has good accel, but then I feel like the engine is rev'd out of the power band before each up shift.  The car pulls in first but then seems to lag when the RPMs get up, then once it shifts to 2nd the car jerks forward with a fresh boost, but then seems to fade again before it shifts into 3rd.  Any thoughts?

At what RPM does the engine start to "lay down"?
