1999-2000 are optimal, IMO. 1997-98 are good; 2001+ are also fine but 1999-2000 had both the wider coast band (intro'ed in 1999) and first design overdrive roller one-way clutch assembly which has larger rollers than the 2001+ second design OD OWC.

Ive read your posts and watched your videos. I’ll take your recommendation as gospel.

Has anyone seen a guide to a swap like mine?
