can a t-14 trans replace a t-96

They are pretty different. I tried this exact swap, and gave up. Too difficult.

hey! here's a clean picture of the T14 installed on the T96's bellhousing. the speedo socket is there behind the box of the transmssion. it's got a plug in the hole (i run electric speedos).

The big problem with a trans swap for the T-96 is that it was only used on the small six bell (41-71 models).  There are only a few trannys that will fit directly, and all are old. Modern Driveline made a run of adapters to fit a Mustang V-6 T-5, but not sure if they have any or still make them. It's a CNC program for them, so they CAN make more, but might be costly if they have to run a single adapter. I think they farm the CNC stuff out. You'd still have to have a driveshaft made and figure out the speedo. Note that the 58-63 American drives the speedo in the opposite direction as the 64+. This corresponds to the location of the drive gear hole. If the drive gear is below the output shaft it turns one way, on top of the shaft turns the opposite. You can swap output housings on early and late transmissions to swap, but has to be like model trannys (T-96 for T-96, M-3x and M4x aluminum autos).

58-63 American, 56-62 big cars have a different trans to bell bolt pattern than 64 American, 63 and later big cars.  Corresponds to four point/three point engine mounting.

Well, since I'm only familiar with trucks, the CJ is technically a truck and even my Eagle is classed as a light truck...Just chiming in with familiarity on the 4WD side. If you read the above about crawling and towing, you'd get the idea that my vehicles do actual work rather than simple transportation. For this reason I think the 199 would be a dog with a T-14. Maybe that's why the CJ that I found with one had a 304 under the hood. This was somehow factory issued. Since time has caught up with all of us, the T-14 is a poor choice all around for a swap. T-15 and T-150 are better choices. The big problem probably isn't the engine but the bell pattern and transmission availability. I would stick with the T-96 until better options emerge but from what I see there aren't any.
