Hey y'all! I was researching overdrive transmission options for my '77, and I came across this: http://www.transmissioncenter.net/gear_vendors_overdrive.htm There's a longish video that discusses various shifter options here: http://www.gearvendors.com/videoclips/sema08-V8TV.html Essentially this is an overdrive unit that bolts onto the back of the transmission. Drops the ratio by 22% when engaged, and adds some 'split shifting' options for you performance types. It isn't cheap, but definitely is a cool new option to think about! And it works with the overdrive trannys as well, giving you even more 'gears' to play with!. I could have used this on my '02 Dodge van when pulling the trailer... my transmission probably would have lasted longer. They apparently have C6, AOD, & other trannys for sale too (and an AOD conversion kit for Mustangs - not sure how well that translates to Rancheros). If you want a beefed up transmission, there are several performance levels to choose from: http://www.transmissioncenter.net/ Just thought I'd share!
