I have a 904 which I rebuild by replacing seal, friction plates and bands. I will keep stock turbine as its almost ok with my slant and 3.55 gears. Little bit improved 1-2 shift is what I like but a higher shift rpm in range 5000-5500 at full throttle is the trick which I really want. Aatrans have parts like modified governor weigth and spring assy. Are those plug and play and you get what you ordered? Shift kit, governor kit, 1-2 shift point kit, kickdown band lever with higher ratio. Please help me with shopping list. I have sent a mail to aatrans but probably they do not give hints for invidiual customers. |

Is the 2-3 shift point where you want it or is that shift early also? DD |

I like to get both 1-2 and 2-3 be higher rpm. Same rpm is fine for both shifts. With my engine fun stsrts at 3000 rpm and if I (manually) let this shift at 5500, engine speed stays in the range. Probably little less like 5000 is fine for traffic light races. |

It sounds like you mite want to call some aftermarket places on a differant wieght set up for the govenor. They should be lighter weights and lighter spring then what you now have. I would think some aftermarket weights would get you close to what you want. They should ask you what gear ratio, tire size, ect. I have a simular ishue but Ive got 2.45 rear 205 70 14s. 2-3 shift at 3000. So Im going to take 10 to 15% off the inner wieght with a valve stem grinder, because my 1-2 shifts are late compared to 2-3. (This govenor that im grindeing on is not a aftermarket set) my 2 cents. |
