DOH, I thought that was pretty much ignored by most.:banghead:
Keep in mind that the spring mod is only good for for later firmer shifts in the low and mid light throttle range, and will do nothing to change the WOT shift timing as that is the governor's job.
I WILL very likely give you a nice little second gear bark though with 525hp under light acceleration.
The valve body changes are really easy if you end up wanting to do it.
Just an adjustment of the mainline pressure valve, block the servo from moving, and a couple of oil passage holes enlarged in the searator plate.
I modded a trans for a guy once that was'nt happy after a stage 2 shiftkit and wanted me to make it nastier.
By the time it was done, the glovebox door would pop open when it hit second from the shock through the body.
Then he was happy.:burnout:
To be honest, I'm a tad flattered that people are using the spring mod.
rayer:
As a side note on the valve body issue I also forgot to mention that I am pushing 524hp and 527 tq through it with a 10 inch 2800 stall converter .so I might be a tad over what the stock was built for eh ? And funny you should mention your little spring mod I copied that page last night hahah
