identifying transmission

86 f250 Idi. Has a swapped 7.3 turbo Idi motor. Backed by a manual 4 speed. Numbers on the trans are adc I e4ya 7505. Can anyone tell me the name of the transmission or what clutch kit I need? Thanks

An E4YA looks to be a Toyo Kogyo (Mazda) 5-speed unit which doesn't seem to have ever been offered by the factory on a F250 but that's OK.

As for what clutch you need, no idea...

Mazda box was offered in SBF pattern only and would not bolt up to an oil burner.

OP says 4 speed. T18 or T19 or NP435 would be the flavors.

What is the case material? Those 4 speeds are all iron and have separate bells. . The ZF and Mazda are aluminum with integral bells.

NP435 has an aluminum top plate where the T18/T19 are all iron.
