Good Morning from Switzerland

I have the following issue with my Ford GT gearbox:

The inputshaft, where the clutch sits are the teeth worn so it has play.

Where can i buy a better gearkit? or a new inputshaft?

Thx a lot for your help!

Alex- the Ricardo gear box in these cars present a unique problem that there are no service parts (other than after market different ratio gear sets) and the guys that know these things inside and out are far and few between. We have a few used transaxles for parts if we can help you but other than that it is a problem that will only get worse as time goes on.

Are you saying the input shaft teeth are worn or the input shaft bearing has play?

It may be easier to buy an entire transaxle from a wrecked GT, rather than trying to find someone who can service yours.

Here is the 3.90 (vs. OEM 3.36) gearset thread. No idea if anyone has a set for sale.

yes i would need the gearset and the inputshaft :)
The teeth of the inputshaft are worn and due to this the clutchplates has play

i only have 788whp... i dont know what gearboxes peopels use with 1200whp biturbo...

Contact David Jones in England. He'll know where to get your transmission serviced.

The 3.9 ring gear, to the best of my knowledge, is not available . Stillen in California was the original source for these.

Alex has been in touch - I've been trying to find a used trans which is pretty tricky over here. I do know of one but the buyer only wants to sell it with the motor its paired with (and right now I don't need a spare motor) - have a couple more threads to follow and will keep searching.

You might check with ABRA Auto Body and Glass (formerly X2 Collision). They move a LOT of GT parts.

This was the X2 Google search before the business change.

They have a complete engine and transaxle on ebay for $30K, which is a great deal (assuming the usual stuff).

AFAIK everybody considers the Ricardo boxes as quite good engineered, since they take HP figures of >1000hp without exploding. The short stillen final gear has been produced only in a small number (and I am not convinced they make fun in Europe since we can drive much faster compared to the US). I am not absolutely sure but I think the Ricardo Tranny was designed new from ground so there is nothing else that is compatible.

Since prices for cars and parts are rising, manufacturing parts for the tranny could be an excellent opportunity for someone who knows how to produce them.

Dude - stop bumping ancient long dead threads. This is over 3 years old.
