71gibby Posted April 19, 2018 Share 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 Link to comment Share on other sites More sharing options...
MC1of80 Posted April 19, 2018 Share Posted April 19, 2018 A 200r4 will bolt right up. No worries to be had there. Quote Link to comment Share on other sites More sharing options...
Blackhawk Posted April 19, 2018 Share 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 Link to comment Share on other sites More sharing options...
MC1of80 Posted April 19, 2018 Share 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 Link to comment Share on other sites More sharing options...
