Yes, I was looking at the Sonnax planetary kit. The 3.06x4.56 roughly equates to a 5.57 behind a T350, so I guess its no surprise that if you hammer it from a roll on street tires, it goes up in smoke . Great for scaring the beejesus out of your Car & Driver type friends, but not overly useful. Sure, you could change to a 3.73, but then 2nd gear shift recovery is going to REALLY go to hell in a handbasket.Alan Roehrich wrote:If the valve body has not been drilled, you can install the Superior kit. If it has been drilled, you'll need a different valvebody. You will need a new separator plate as well.
Yes, the bigger valves will help.
Sonnax now has a new planetary set that gets rid of the excessive 3.06:1 first gear, and changes it to something much more manageable in the 2.7:1 range, also narrowing the drop between first and second gear.
Alan, not trying to be a PITA, but curiousity forces me to ask, what specifically is wrong with the transgo kits? Pretty sure I will need another valve body, but thats not a huge deal...
