I'm looking at it this way. All the newer (auto) trans from Mopar used in the high performance cars are using 7 and 8 speed transmissions. Look at the low gear ratios and how they split the gear ratios all the way up. AND, they are using a final gear ratio like a 3:25 or something. Here's the advantage to this setup that makes total sense to me. Lets say a low gear ratio of (just saying) 5.0 to 1 and split up all the way to overdrive. With that low gear ratio you can now launch the car like a 4:56 rear gear BUT, with that 3:23 rear gear drive shaft AND the ring and pinion speed is very low not singing high tones, spinning like crazy. I bought the 6 speed trans but really didn't want to or do I like it. GEAR RATIOS are all wrong for a street car that also wants to go the freeway or across country drive? Long ago when I bought that 6 speed I talked to all aftermarket trans companies on why don't you make gear ratios like I want. 5.0 on low then split to 5th or 6th that is 1 to 1. Now run a ring and pinion of lets say 2:90 or 3:40. Now the car will launch well and going down the highway won't be singing high "C" with the driveshaft and rear end!!! U-joint DO suck up alot of HP! Everyone I talked to looked like deer in the headlights------------ had no idea what I was talking about? SO, for most cars made for the street the 5 speed has only one overdrive, no need for the 2nd overdrive gear. There is alot of what info is, what and how does this all work together. And as usual there is twenty different ways to go about this. SO, GOOD LUCK with everything.
