iv got a 87 4runner with what i expect is a W56 trans, can other transmissions bolt up in its place? I found a R150F out of a 3.0, also 5 speed top shift. Also my brother told me to get a "T5" transmission?
If you have a 22RE engine you have a W56 trans.
Around 89 the W56 was changed to mate to a forward shift t-case. It would still bolt-up and work but you'd need the t-case too.
