I got a great deal on a B&M 2400 RPM holeshot stall convertor for 280 bucks! Does anyone know anything good about this stall? Is it a lockup or non-lock up?

fordguy17

its prolly lock up but go bigger. at least 2800 to 3200.

good lol im not the only one. i get the lock and non lock. but whats the diff, what do they mean?

fordguy17

in an aod the converter locks whenever you it third gear.basically the two sides lock together to elimante all slippage, reduced heat, and increase gas mileage.

turbo cars love lock up because of the extra boost that can be created.

Tims 88GT

so a lock up locks the 2 side of the converter togeather? so there is no slipping. but this only happens in 3rd gear?

fordguy17

on a stock aod yes. it locks in when you hit third and also stays locked in in fourth.

it will unlock again once you drop into 2nd or 1st.

Sweet GT Fordguy... The Rodlites and hood look great...

ok sweet, so if you get an aftermarket lock up will it lock in 1st and 2nd?
