MG TD TF 1500 - TC Trans in a TD

Does anyone have any sort of plans for the necessary modifications to the transmission mount area of a TD for installing a TC transmission? I don't want to reinvent the wheel if something already exists out there.

Thank you.

Contact thr MGVR racers on Facebook...a number of them have made the conversion.

I am not familiar with the TC tranny. What does that gearbox do for the TD?

Hey now, TC gearboxes are already rare enough. Don't go putting ideas in people's heads. ;)

Tom,

The TC transmission is more robust than the TD transmission...many MG vintage racers use them in their TDs.

That's interesting. I thought they were all the same. Just the standard Nuffield box of the time, but different ratios used eg close ratio in MG, wider in Riley 1½ etc

The TC box is completely different in shape and construction than the TD/TF box, and the TC box is considerably more robust. Virtually nothing is interchangeable between the two.

Unfortunately, everything I have been told indicates that the TD chassis cross-member must be partially cut out, and a new bracket welded in for the TC mounts. Also, the drive-shaft must be lengthened.

There are very few parts on the entire car that are the same between TC and TD! It's truly a completely different design, despite some visual similarities.
