If you want a truly high-performance AOD, the Transgo AOD HP kit and one-piece shaft with a C6 converter will be best. A tight 10" variety is best for performance street driven vehicles. One thing to stay completely away from is putting the 4R70W gearset into an AOD. The governor is a linear type and the shift valves in the valve body are sized to work with the close-ratio gearset. An AOD with 4R70w gearset will have poor shift timing that cannot be corrected. Setting the TV is critical as well. It must be 0-1psi at idle and just make 90psi at WOT, as soon as you let the throttle back from wide open the TV pressure must drop. Throttle goes 90deg, TV pressure should match the throttle angle within 1-2psi. Also important, especially in stock shaft/converter units is the 3-4 and 4-3 holes in the plate. A 4-3 thump will eventually strip the splines and a 3-4 slide/flare will eventually burn the FWD clutches/OD band.

The 3-4 and 4-3 shifts are tuned by driving the unit and evaluating shift feel. Once you determine if you have a bind or cutloose on each one, you have to change the hole sizes indicated in the instructions for each. These transmissions take some work to get _perfect_ but once you do, they LAST.

This is great!!

Do shift kits hurt the transmission any?

[@williamblanks8500]

Most shift kits are designed to prevent known transmission failure points.. so they should actually make ur transmission last longer..

So in my 06 Crown Vic I have a 4r75w transmission, would it be best if I installed an actual shift kit or just get the transmission tuned with an SCT X4 tuner for firmer shifts?

[@williamblanks8500]

They both serve different purposes.. a shift kit is a shift improvement kit and a preventative maintenance kit in one.. on certain transmissions that are electronically controlled a tuner can perform so of the same duties such as make shifts firmer and adjust line pressures.. but that being said the best advice would be a combination of both.. if it were me I would install the shift kit first, then adjust everything with the tuner from there.. mainly because some shift kits come with parts that will prevent ur transmission from failing that just don’t come with a new tune.. one example is on certain transmissions won’t pass transmission fluid over some gears while in park, this will cause the gears to run hotter and dryer and cause them to fail earlier, most shift kits would come with a bypass to prevent that problem if that were a common problem for that transmission..
