My transmission is reported to have a broken 1st gear. Not uncommon.
I've taken one pass through the EvilWerks videos (I bought the series) and as best as my memory can provide - the 1st and reverse gears are under the outer cover and not nested inside with the rest of the gear clusters. So, here's the question: If the damage is limited to just those components can one do a diagnosis and repair without cracking open the whole gearbox? Obviously if upon inspection things like synchros, etc are worn I'm all in, but this trans is reported to be sound other than the broken 1st, but yeah, race car... Any transmission repair advice welcomed. Thx. |

We didn’t go with a kit
We found a good cooler and had it cleaned Made up our own SSI lines and fittings There is a farm pum sold at the farm and ranch stores that is all the same specs (housing and even dimensions) as the Tipton pump Farmers use them to pump weed treat and fluid transfer on big commercial sprayers. It might be the same pump manufacturer But it’s half the price of the Tilton. Just no Tiilton sticker We had our guy drill holes in the case over the stack/diff/etc He didn’t even put in a spray bar And he has used the same set up on nearly a dozen 901’s The AN fittings screw into the holes he drilled and tapped I don’t remember the AN size. Probably -8 The cooler should be sized for the same |

Great ideas. Thanks. I imagine a significant benefit is simply having more oil capacity and it being cooled is a plus.
