When you add the fact that this car is a manual, it really makes this drag racing video a rare one to enjoy. When doing burnout's you need to roll up to the water box then shift all sections accept the front section. Air servos or max-adjust shift towers. The sun gear is the center of the mechanism's universe. 1.48% ratio uses 22 tooth planet gears, a 40 tooth sun gear and an 83 tooth ring gear. If it is necessary to remove the servos you should reinstall with the lock nut spun completely to the top of its travel. This L.. Lenco Clutch Disk Alignment Tools areavailable in black anodized billetaluminum. 1.48% ratio uses 22 tooth planet gears, a 40 tooth sun gear and an 83 tooth ring gear. Each sun and planet gearset represents two speeds. You always need to come out of the water box in high gear to prolong the life of the transmission. It is also 2-lbs lighter for lower rotational mass which translates to quicker acceleration. Add fluids as necessary and install fill plug. 1.338% Uses 24 tooth planet gears, a 25 tooth sun gear and a 74 tooth ring gear. 1.19%Uses 21/33 tooth planet gears, a 22 tooth sun gear and a 76 tooth ring gear. (1) in the bruno/lenco the fluids are seperate - which gives you options of running different fluid types and no chance of breaking the lenco side and mixing it into the converter. You can add additional cases and gearsets that will result in 3 or 4 speeds. Air or Lever Shift. 1.48%Uses 22 tooth planet gears, a 40 tooth sun gear and a 83 tooth ring gear. It is not necessary for the driver to disengage the clutch when shifting from ratio to ratio since all shifting is done with the engines clutch fully engaged, R577980 Raybestos Gen2 (Blue) Lenco celebrates over forty-five years of the engineering and manufacturing of the most successful drag racing transmissions ever built.
