Sorry for the hijack, but this is turning into a good trans thread. When I bought my car the previous owner already sunk $8k into the 901 trans. So I am kind of stuck for now. Isn't there a gear flip option to make 5th gear higher so it doesn't rev so high? When I get a chance I will research the other threads. I know the 901 turned into a four speed, eliminating first is still popular with the v8 crowd.

Installing a flipped H gear is the most economical way to make a taller 5th and is a popular option. The only other ways, besides the H gear, to get a 901 to have taller gearing than stock is to either have custom gears made, or find the correct year auto tranz and grab the smaller r/p out of it.

So you should be able to physically replace it. The only tricky one for the 901 is 2nd gear because it's attached to the main shaft. |

Dumb question Mr. Evil, but where might I find an H gear? What make and model did it come in? How hard is it to change? Enquiring minds want to know. Do I need to pull the trans or would all the guts slide out the rear? Hate it when that happens (IMG:style_emoticons/default/slap.gif) |

Steve, if you are unfamiliar with how the guts go into the box, you need to read up (IMG:style_emoticons/default/wink.gif) You would need to remove the whole stack and do some serious work to swap the gears. H gears are for sale from me, or other gear vendors like carquip (see link in my sig).

That is why you are left with flipping a 2nd gear (H). |

You must call for pricing. Prices vary from $300-500.
