Hi all.
Unsure if that is how it is named, been told it is a 'Holdback' type of automatic transmission, when releasing the throttle pedal, the vehicle does not coast freely but a drag is felt.

What component in the transmission/other implements such behavior ?
My other cars (GM) just glide with no throttle applied, coasting forever.

'Holdback' may be a convenient feature for cruise control behavior on downslopes, but see no other advantages. Are they ?

Is that typical for a 2000 Disco ?

 

The hold back you mention is the TC, and this is correct, it doesn't unlock upon release of the throttle. Because of this, engine braking will slow down the truck, much the same as letting off the gas whuld while in gear on a manual transmission equipped vehicle.

 

You are driving a big brick, aerodynamics will slow you down, this is not a feature of the driveline, it is just the way it is.

 

He's trying to refer to the "coast band" in transmission of other cars he owns. Where you let of the throttle and the RPM will be allowed to go to idle.

 

Thanks, guys.
The 'holdback' effect happens at any low speed too, before the torque converter clutch is engaged. Cannot be the reason.
On a downhill, shifting to neutral the 'holdback' goes away and vehicle coasts freely or even speeds up, so it is some transmission 'feature'. By the same reason, should not be axles/differentials drag.

My other cars are heavier bricks, but more aerodynamic. Aerodynamics could prevent the vehicle to coast longer or gain speed downhill, but not to feel the 'holdback' when releasing the throttle.
Yes, other cars get to nearly idle when coasting, The Disco does not.

I will take it as the nature of the beast.
