Hi folks,
A few weeks ago I told you about a tranny conversion for a TR6 and promised to
get further information for the list. Sorry for keeping some of you waiting,
but
my job kept me really busy.
The gearbox is modified by a German company, I called them up to get more
information. The gearbox is the 5-speed box from a Rover 3500 or late TR7/8. To
use it in the TR6 (TR3/4/5 as well, but TR6 clutch needs to be used) they use a
different bell housing. The owner of this company did not tell me which bell
housing he is using, that�s his big secret! So it�s up to us to guess which one
might fit. The clutch slave cylinder is on the right side and therefore the
�routing� of the exhaust pipes have to be modified. No modification on the
chassis frame are necessary. The TR6 rear engine plate stays in place, but I do
not know whether some minor changes (e.g. holes) are necessary. The gearchange
lever mechanism is a shorter than the Rover 3500 version to match the TR6 lever
position. (I�m not sure whether a late TR7 5-speed lever is shorter than
Rover�s). The propshaft needs to be shortened and re-balanced. Slave cylinder,
starter, fly wheel and clutch are used from the TR6.
The advantages of the tranny conversion:
- due to the needle bearings means more power at the rear axle;
- less weight better acceleration, higher mileage/gallon;
- no overdrive necessary;
Anyway, the company make a big secret of their 5-speed conversion. They offer
the complete modified and reconditioned gearbox including the bell housing for
D-Mark 2000 (= USD 1190, ex. Ratio 1USD=1,68DM). This is a fairly good price if
you consider that the tranny has been rebuild, modified and comes with a
different bell housing.
Unfortunately, they do not have any brochures or other information in English.
But for those of you, who are interested to get more information I will help
you
to get in contact with this company or I will do that for you. (Oh yeah, no
financial interest of cause!).
I hope that helps.
Best regards,
Jochen
