T-9 Fill information.
Prior to 1987, T-9s had a fill hole thst was 24 mm above the recomended fill level.
(Photo on Left) This required the use of a dipstick to measure the fill level. A PITA if the T-9 was in a Seven.
FWIW: The Mercury Merkur called for 2.3 qts. of gear oil.
They can also be identified by the yellow paint square on the left side of the extension housing.
After 87 the fill hole was lowered 24 mm to make the bottom of the fill hole even with the proper fill level. (Photo on Right) Hence, the confusionusion over the concept that it is correct to "Fill to the hole."
Obiviously if a pre-87 case was filled to the hole it would take more fluid than necessary.
A simple method of determining if you have a pre-87 or post-87 case would be to take a simple measurement of
the bottom of the fill plug straight down to the bottom of the case.
Pre-87 Case Post-87 Case
Another means of identification is the the main design feature of the "late"
transmission 1987> was the modification to the counter shaft support (now
using a bolt-in spigot and caged roller bearing in place of the loose needle
What about the diffeent imput shaft lengths?
Most kit cars are designed for either the short input (4
cyl) or long (6 cyl) European T9 transmissions. The T9 transmissions most
commonly found here in the USA are the Merkur XR4Ti type, which have a unique
input shaft length midway between the European 4 & 6 versions. Scorpios
bound for our shores, 99% of the time, came with automatic transmissions. Using
a XR4Ti T9 can pose problems due to this odd input length. It often pays to
purchase the right transmission from the kit manufacturer or recommended
installation kit for your car.

Quantum Mechanics Ltd. was formally
established in 1981 to support a 20-year ongoing racing program that
included at that time a Lotus Super 7, a Triumph Spitfire 1300 and a
1275 Mini Cooper. We rallied and raced in EMRA, SCCA, local club
Gym-khanas, auto-crosses and time trials and other car events (even
economy runs!) and in the winter competed in ice-khanas and ice races
throughout the Northeast. Although we no longer race ourselves, we
currently design and build many racing transmissions for many British
Right now our primary focus and work is on production British car
transmissions, especially overdrives. We supply parts, rebuilt
transmissions and overdrives and provide expert advice to British car
and race enthusiasts worldwide. Some British car Marques supported are
all Austin Healey, Austin (Mini), English Ford (and derivatives),
Morris, MG, Triumph, Jaguar, Morgan, Lotus, Rover and a few other
British cars and other cars that use British transmissions (Ferrari,
Nash Metropolitan, etc.) We have over 35 years experience in British
cars and currently build between 200 and 300 transmissions per year
worldwide. We have contracted with parts manufacturers and machine shops
in the USA, Australia, New Zealand, Germany, England and Italy that
supply us with new, reconditioned or remanufactured parts for these
transmissions. We have over 200 core and rebuilt transmissions in stock
at any given time as well as thousands of British transmission and
overdrive parts. We also do some specialty carburettor work (such as
Spitfire 1500 twin 1 ½ inch) and differential work on TR6, Spitfire, GT6
Our goal is to provide high quality parts, services and professional
advice to allow enthusiasts to continue to enjoy the British car
tradition. We consider ourselves enthusiasts first (We currently own a
Sunbeam Tiger and an Austin Mini) as well as a professional business. We
support many local clubs and events and wish to help continue the
British car motoring tradition. We enjoy the work and look forward to
meeting with other enthusiasts. Our hope is to have a positive presence
and impact on the overall environment of classic British car ownership.
