Anyone know if there is an aftermarket engine brake, or jake brake, that can be fitted to diesels?
All my previous diesels have had real strong compression so going down hills was a breeze. Drop it down a gear, and bobs your uncle. No braking needed.
This current diesel (Pajero 3200) just goes faster and faster down hilll. Unless I'm riding the brakes or almost red lineing it in a very low gear, it easily over shoots the speed limit.
I did think about putting it in four wheel drive, but that was after I got off the mountain.

Hello SDG,
I too own a Pajero and yes if you are driving in full Auto, they show little engine braking ability. If you are towing then I could imagine it would be exaggerated further. Suggest you read owners manual about towing where in it recommends using semi auto (sports Mode) and 4wdH and gears 1-4.
I tow a 21ft van and am close to my load limit. I have been over some pretty steep country and have found the auto system used as per the manufacturers spec as good as a manual but easier and quicker to use.
Happy driving.

no idea champ..
copy pasted it from lcool mate.
your on their too arent you.

hey you stole my truck, painted it red and put a ally tray on it..
bastard.............. ha ha

damienperu in his troopy getting it fitted at the moment, latest i heard..

id rather the screamer jake brake myself, get the old 2h sounding like an old mack.. straight out the manifold.. ha ha

other option is nomad kit through the pajero auto, better than a manual, and super strong, with better oil flow..

mountainman, used to be - haven't been on for a while

agree with you, I reckon the 2H would sound mean with the air brake :-) - mind you having done the the whole of the Anne Beadell in my old troopy with a sizeable hole in the mainfold, I'm not keen to subject my ears to that again in an awful hurry......

I fitted one of the auto lockup units from Wholesale Automatics in Bayswater to my 4.8l petrol auto Patrol.

To be honest it don't do much at all in high range and sometimes you feel that you are going faster. It is good on highway running as you can drop 200 - 300 revs when touring.

Not complaining about Wholesale Automatics as I chose to have it fitted. It was just a bit disappointing but petrol engines do not have as much natural compression braking as diesels so it might be better in the Paj.

If you fit one watch out for the fact that if you forget to turn it off when you are slowing down, say for slow traffic or lights, the car will stall.
Happy 4 wheeling

Just a follow up, and thanks for the answers, but I drive a manual.
I do like the idea of the first one, which i'm going to follow up on.
