Manual or Automatic,thoughts please.?

Sounds like a good plan. Personally I have always driven Manual unless forced by company cars etc etc. This thread has made me want to move to auto in the future. Why work harder, it's a work truck not a bare bones sport car

Jake Brake? 

I'd love one, thanks. But it's really a compression release brake. Engine braking is strictly speaking the closing of a throttle valve causing manifold vacuum.

 

As for shiny modern pickups... A box of chip and towing 750kg shouldn't be taxing for any of them. Ive only driven older rangers but the manual boxes have always been horrible, so try the auto. 

Hopefully you have a good local ford dealer in mind, newer rangers are not renowned for their trouble free motoring ask PeteB about his experiences.

Variable oil pump failure by any chance?

I thought engine braking was when you close the throttle and the road wheels are now turning the engine rather than the engine turning the road wheels . Going down hill for example . The higher compression engine you have the more the braking effect will be . Try going down hill off the gas in say 3rd and then try the same in neutral .

Regardless of the exact mechanism, and mostly from experience of 1970/80's tractors, using the engine in lower gears gong downhill, worked better than the so-called brakes connected to the brake pedal.

My understanding was that a diesel engine  without fuel being injected acted like a positive displacement compressor, which will require significent energy/work to function, and that the Jake brake merely enhances this effect.

And now I gotta go and establish exactly how  a Jacobs brake works, thanks Clessie.

If I understood the rather poor explanation, the Jake brake overrides normal exhaust valve operation, such that each upward piston stroke is a compression stroke, the valves only being opened to release the pressure after TDC, is this correct?

Jacobs brake, engine exhaust operated brake possibly Hebrew in origin from the Horn of Jericho. K

Auto every time,  my last 2 Discos have been auto diesels,  plonk it in drive and off you go.    I pull trailers loaded to about 2.7 tonnes 3 or 4 days a week,   no downsides at all.  

 

But its a one way street,  its a pain having to go back to a manual.

Jake brakes basically change the exhaust valve timing so instead of suck, squeeze, bang, blow its more like a Suck, Squeeze, Squeeze, Pop... Don't start me off on euphemisms here. 

 

It keeps the exhaust valve closed on the blow/exhaust stroke and then the valve pops open when the piston is near the top so you effectively have 2 compression strokes, one after another. More compression=more braking

 

How any of this helps a guy chose between manual and automatic I don't know 😂

I've got a 2016 ranger 3.2 t6 manual.The heaviest I tow is a 28 ft caravan it returns 30mpg tows like you wouldn't know it's on the back.only thing to remember is if you do your own oil change you got to drain and fill and have the engine running with in 10 mins also check for oil leak at the bottom of the bell housing it will be rear crank seal leaking quite common fault other than they're awesome to drive.
