I did it myself using the conversion with the separate filter. Hacksawed off the old filter neck, etc. Heat shield bolts were a big PITA, so was sawing off the filter neck. After all is said and done, it was a big sense of accomplishment! Leaks can sometimes come from the back top of transmission where there is a racket ball sized plug/collar that surrounds a snarl of wires going into transmission. It was too hard to get to for me to replace it though.
The kit surprises you saying you need a tap to ream out all the cover holes, but comes with new bolts. The original bolts are longer and there is crud in the upper reaches of each bolt hole. Reaming the hole with the tap was well worth the effort vs. using the new bolt to do the work. If you watch the video, pay close attention to seating the new filter neck. Re-filling the transmission is also PITA, due to hot catalytic converter waiting to burn your hands, wrist or arm. Put some kind of heat shield over it before filling and putting back the plug, another ordeal.
