| Although the MD4S-2D transaxle is the
best buy on the market for cars in the 300 to 500HP range there are many reports
of failing main bearings from a variety of builders. This failure is caused by the tremendous side
thrust of the transmission main shaft, generated from high performance motors.
Such failures usually require a complete transmission overhaul. If you
have such a failure it would be wise to consider including the "Funco Fix" to
your 2D trans. |

| Funco got
involved with this situation because of the number of cars they build and
support. They needed something to help keep their customers happy when using
the Mendeola MD4-2D transaxle. So in desperation they engineered a new
transmission nose cone they believe is a "fix" to this main bearing situation.
This upgrade kit utilizes a Timken tapered roller bearing to add more support to
the main shaft. The kit also replaces the standard
main-shaft end-nut with a custom nut with milled race that mates to the roller
bearing. This new setup applies a slight pressure to the end of the shaft,
off-loading the main-bearing from the extreme thrust pressures that can
overstress the main-bearing. The result of the kit is a longer life to the
main-shaft bearing. It's important to
know the kit lowers the shift shaft about 3/8" of an inch and requires a
minimal amount of shift linkage adjustment (rotation).
This "Funco Fix" is
not for Funco cars only, it's useful in all MD4S transaxles.
The kit cost is $450.
