Toyota had love for the W Transmission. Various versions were used over 34 years of production. That is sick! And it means there are tonnes of variations and gearsets available for us to potentially play with and perhaps make a real close ratio gear box. Well... almost... or so it appears.
First of all... I couldn't find solid documentation on the early W4X and up to W52 transmissions, but they look to offer additional ratios that may or not be helpful. How those ratios would play out with W55 or 58 input shaft ratio's though was unclear. Someone is going to have to pull one apart and figure it out.
