My TR4A has a nice torque-y engine and I am pretty sure it would be quite happy at 0.75 and maybe even a lower ratio than that. So, for $4K I think, personally, I would have my tranny rebuilt and retrofitted with the electric OD</div><div><br></div><div>-Tony</div><div><br><div><div><br><div dir="ltr">Sent from my 1837 Babbage Analytical Engine</div><div dir="ltr"><br><blockquote type="cite">On Jan 2, 2020, at 3:26 PM, Randy and Valerie DeRuiter <deruiterville@hotmail.com> wrote:<br><br></blockquote></div><blockquote type="cite"><div dir="ltr">
