Th400 and stall/gear question... Looking into the TH400 but ive been outta the loop on the A4s for a while...much less the A3.
Motor being my 408ci...what kinda stall/gear combo could i run to get good track times but be somewhat decent on the street. (ie keeping rpms around 3-3500 @ 65-70)
Polly will be a RMVB with a Tbrake (maybe
)
right now i have 4.10s but thats no problem to change.....
suggestions?

that if not....it puts alot of excess heat on the tranny....

and are you on a auto/man valve body or full manual?
and how is the looseness of the 2 stalls around town?

switch pitch in most torque converters the stator is fixed and you have one stall speed. with the switch pitch the stator blades change angles giving a low stall and a high stall. say 1800rpm and with a switch 2800rpm. the only problem is it is only available for the th400. fyi

Mine is about
5300/5100 converter (had it tightened up but still drives about the same) 4.10 gears 31 inch tall tires-------> 3000 rpm at 60 mph / 3,500 rpm at 70 mph.
Driving around town is no problem at all. i drive it 90+ miles a day every day. tranny temps depend on the weather. anywhere from 160 to 200. But i'm in Texas so that 200 is on a 105 degree day.
