ive got a torque converter lock up switch..
it keeps the torque converter unlocked when in manual
things you notice:
about 30kw on the dyno
acceleration is much better
holds gear(obviously)
but does drink the fuel
more importantly why i did it was because it keeps the auto trans cooler flowing
so now i can lock the torque converter and cool it from the "extra stress" i give it. lol
Scott did it for me.. i think me and him are the only people that have done it so far...
best thing ive done
