I have a 00 mustang 3.8 4r70w with a 75 shot, some bolts ons, and stock 3.27 gears. I dropped the tranny for a PI 3k stall and to mod the valve body. 36k miles on the clock, changed the fluid too.
I read the articles several times and borrowed a friends transgo video to get an idea of what I was doing. It was somewhat confusing trying to figure out what you're supposed to do for X year, I got the impression my 99+ VB had all the other good stuff so I didn't need anything but the larger holes?
Jerry mods to seperator plate only, drilled holes to following spec:
hole/stock/mod
1 .160 same
2 .060 .100
3 .160 .180
4 .080 .100
5 .080 .100
6 .130 slot
7 .080 same
8 .238 same
9 .081 .089
10 .075 .083
11 .070 .089
My car was already rough on the 1 manual downshift with the stock converter, so I left that hole alone. Wasn't too keen on jamming into reverse so I only made that one a little bigger.
The car does not bark tires, but I do have a 3k stall converter and soft tires with a 140 treadwear ratin (RE71s), it shifts very nice, goes into gear quickly at WOT and part throttle is almost smooth as stock. My only issue is it shifts earlier. Stock shifts for 1-2 and 2-3 where at 5600, now they are at 5200 and 5400, a little too early. Did I do something wrong or is that just the accumulators filling faster?
Thanks
