I purchased a '94 2WD E4OD trans for the 'M' block motor in my '53 F100. The trans didn't have a tail housing, so I purchased a tail housing on Ebay with a speedometer hole.

When I try to install the tail housing, it hits the large reluctance wheel on the output shaft.

The transmission case casting # is RF-F0TP-70C6-AB.

The tail Housing is RF-E9TP-70C6-CB.

Do I need a different Tail Housing?

Or do I need a different Speedometer Gear?

Or do I need a different Output Shaft?

I can use either a VSS or driven gear for the speedometer in my truck.

 

What Transmission is this?

I thought that it was an E4OD, but it may be an 4R100. That Reluctor Wheel will not fit my E4OD Tail Housing. This trans fits a 460 motor.
