Sprint Engine adaptor plate

#1 Post by new to this »

Is the Sprint engine adaptor plate ( engine to gearbox ) the same whether auto or manual ?

Thanks Dave

So do you mean the engine bolts straight to the gearbox ?

Yes.

The purpose of the adapter plate in manual cars is to locate the remote box ( gearstick ) in an ergonomic position; the ‘box was borrowed from the TR6/Stag/2000 and it’s why the Sprint ‘box has a longer input shaft compared to the other cars.

By comparison, the automatic ’box has a separate selector lever connected to the gearbox via a slender adjustable length rod so the position of the ‘box doesn’t dictate the location of an integral selector.

The cars with straight six or v8 engines have longer blocks which naturally place the manual stick in a convenient/comfortable location.

Were both the 35 and 65 auto boxes fitted to the sprint? What I mean is does the sprint autobox have a removable bellhousing?

Just the '65 I believe, but yes, the bell housing is a separate casting to the main case.

The 1500, 1850 and Sprint have different part numbers for the bell housing.
