71gibby Posted April 19, 2018 Posted April 19, 2018 I found this trans locally. Seller stated it will not mate up to a SBC motor. Is this true or is there some sort of adaption required? Thanks Jim Weird, post didn't show Topic. Anyway it is a THM2004R. Quote
MC1of80 Posted April 19, 2018 Posted April 19, 2018 A 200r4 will bolt right up. No worries to be had there. Quote
Blackhawk Posted April 19, 2018 Posted April 19, 2018 It could be a THM200-4R with a BOP bellhousing rather than a Chevy or dual patterned bellhousing. This thread gives some information and photos on the differences: https://www.jalopyjournal.com/forum/threads/200-4-r-transmission.566029/ Quote
MC1of80 Posted April 19, 2018 Posted April 19, 2018 I have only seen the dual bolt pattern on the 200 r4. The metric 200 was a 3 speed and engine specific. Ie- Chevy pattern OR BOP. Quote
