The type 336 transaxle contains mostly Renault but has several "Lotus-only" Renault
parts. The most important difference is the opposite rotation of the crown wheel as opposed to
the applications in Renault vehicle, due to the rear engine location of the Lotus.
The types 352 and 365 transaxles are 100 percent Renault with no "Lotus-only" parts.
The type 336 transaxle was used as the associated gear shift linkage is more precise and
less vulnerable to damage in rear-end collisions. The five speed transaxle was not legal for
SCCA racing in the 1972-1973 season.
Straight-cut, close-ratio gears were used with no synchromesh. It was necessary to relieve
the transaxle casing to provide clearance for the input shaft third speed gear. A maximum end
float of .005 in. is desirable in all gears and shims may have to be used to eliminate excessive
end-float. All roll pins were safety-wired for security.
The transaxle casing was drilled to accept 5/16 in. UNF bolts. The gearbox was
assembled using Hylomar jointing compound.
No limited-slip differential was found necessary and the standard differential was used.
The differential was assembled with .0005 in. end-float in each axle shaft. This was achieved by
machining crown-wheel side of differential housing and
