That means the torque converter will not start pulling until the engine reaches 2800 RPMS. Nother words transmission will not start pulling.
2800$$
if you got an automatic depending on what gear it is you may need a 2800 or 3500 rpm stall in your torque converter call a transmission shop if that's it they will help you
My transmission change through the Ford dealership was about $2800.
Bad seal? Bad cooling line to radiator?
if you have an automatic transmission depending on what gear you put in it from stock if you don't have like a 2800 or a 3500 stall in your torque converter once you get off of the line it will fall flat on its face i would get a 3500 stall torque converter call a tranny shop and they will help you out if you have a manual transmission then you probablly got a vaccum line of some kind unplugged check all the simple stuff first its the simple stuff that will get you trust me.
fuel filter
A very low idle can cause a 97 Ford Taurus to stall. Another reason for stalling may be transmission bands sticking, which does not allow the transmission to come out of gear on idle.
Failing transmission
balls. balls will slow shafting
5% of 2800= 5% * 2800= 0.05 * 2800= 140
70% of 2800= 70% * 2800= 0.7 * 2800= 1,960
36% of 2800 = 36% * 2800 = 0.36 * 2800 = 1008
