Easiest way try free myself of my sm465

[ViviensTractor5110]

Ok, ok....I know...legendary transmission...bullet proof. Trust me I am awed by the beating they take and of how simple they are. No disrespect to the venerable 465.

That said...I recently put a nasty 400 sbc where a 250 one resided and I want to bang gears. My truck is a swb 69 with an original bell housing, manual x member ect.

A tremec with overdrive would be ideal....too pricey.

A turbo glide or th350....for the price I might do without overdrive and grow to like a ratchet shifter.

How bad is an auto swap.... xmember changes? Resize/ balance a shaft? Anybody been where I'm at?

Thank you in advance.
