can still used my old a/t trany ?

[pinoy nismo]

have two silvia, a 240sx a/t with ka24e and a s14a a/t sr20det........ i just bought a sr20det redtop with manual trany........ now this is my plan the redtop and the trany will go on a separate way, ill converrt my 240sx to sr i plan to use the stock auto trany, will the sr engine be a bolt on with my stock ka trany? and  can i hook the a/t ecu to the sr ecu?..........at the same time ill also convert my s14a automatic to manual using the m/t from th sr redtop...........and can you (zilvia peeps)  tell me what problem should i expect when doin all of this stuff.   thanks..........

i think all of that should be possible EXCEPT for the ecu because the ecu will be completely different.... u need to get auto sr ecu and 5-spd s-14 ka ecu

the bellhousings on the ka and sr trannies are different.
