re ratio
the stock factory gear ratio in a c6 transmission is as follows
1st gear 2.46:1
2nd gear 1.46:1
3rd gear 1:1
if you get a wide ratio gear kit you can change it to be lower and make the transmission almost bulletproof. i have done extensive work on my c6 and still not done yet. i`am trying to eliminate all the friction i can because it takes about 70hp to run a c6 transmission in stock form. i have replaced the brass thrust washers with turrington bearings changed the output housing to a needle bearing instead of a bushing (from a lincoln) installed a 6 pinion front planetary (stock in only3) have found a orignal ford 5 clutch forward drum (stock is 4) updated the rear planet to a 4 pinion instead of stock 3 and installing heavy duty e40d(4r100) internals fron big block or diesel should last forever behind a 302
the wide ratio gear ratios are as follows
1st gear 2.72:1
2nd gear 1.54:
3rd gear 1:1
1st gear 2.46:1
2nd gear 1.46:1
3rd gear 1:1

original ford 5 clutch forward drum (stock is 4)
[B] Actually, the heavy duty is four clutches and most regular duty are only three so you made a score.
Updated the rear planet to a 4 pinion instead of stock 3
[B] The best one is the steel 6 planet in the new Super duty (F450 and up) but the Aluminum 4 planet is good for 500-600Hp I am told.
Also you might want to get the 'R' code servo piston set up from Ford motor sports so the band will keep up with the rest of the trans.

Good list. Could you email it to me? brandonmoody@mindspring.com Here's some more info to help the list. The 4r44E/4R55E were also used in the Aerostars. I'm not sure what year they switched from the A4LD but I know the 87 model had one, and my 96 has a 4R55E. Once again, good job!

4r70w
Hi,
When I did my first tranny fluid and filter change at 30k miles, I went to my local auto parts store and told them what I had and they told me to go to the dealer. I called the dealer to find out what kind of tranny I had and they said I had an AODE. After looking at the tranny pan last night, I realized that I had a 4R70W with an orange TSB 98-4 sticker on it. All of my other fluid and filter changes, I have been able to get the fluid and filter at my local auto parts store after the 30k mile change. I now have 134k miles on the truck and it still runs good. I have minor tranny problems that I posted and hope I can find the answers here on FTE.
Thanks,
Chris

Would like a gear splitter with overdrive, Surely someone out there has some info on this, don't you all answer at once. live in iowa so hills aren't bad here but southern mo and ar is where we need some help thank you all Halsey
