Hi Folks,
I posted previously on 21257 re performance enhancement options and I must give some feedback. Many thanks to Chaz, Tigertough12, & Captain for their valued comments.
I have fitted a Dtronic unit and the Patrol Roars like a bull. Has plenty of available low down torque and great for towing.
As our new rig is an auto there is a need to have the kick down sensitivity adjusted as going up steep hills the kickdown is somewhat premature.
I don't know if it was just bad luck but I blew an air hose off between the turbo air compressor discharge & the intercooler inlet...going up the big hill into Toowoomba...and yes had to get a tow to the top as semi's were having to stop, quite a fiasco & very unsafe, just on dusk.
Found out that ALL the hose clips on all the rubber hoses on the turbo discharge were very loose.
Hence something for others to be on the lookout for & check etc.
cheers for now

Yes. Happened to me while towing a jayco camper, about 25k out of roeburn (lovely place, NOT) All hoses were loose. I don't have a dtronic fitted.

Have exactly the same rig including the colour.

How do you go for warrant with the Dtronic fitted.

Find mine very hesitant to take off but once you are moving, no problems.

I guess you will always run that risk, however the Dtronic can be installed & removed and the only evidence is a "velcro" attachment patch which has only double sided tape. The unit is very skillfully engineered to go downstream of the OEM computer with very high quality in-series plugs. No cutting of any wires at all or running power supplies etc.
I fitted mine in 20 min in the car park after I bought it. ( Did not want the navigator to find out.....$$, had enough probs with upgrading the patrol. )
The only difficulty was working upside under the dash with my crook back. Otherwise it is a great enhancement.
good luck mate.

Hi Donald,
Great to hear that your happy with the Dtronic, and regarding your inquiry about the Patrol shift kit, as I see it you have two options. You could fit a change over modified valve body, or if you have a bit of mechanical ability, you could fit the kit to your valve body yourself.
Check out this link: regarding change over Valve bodys on eBay or for change over valve bodies in Victoria.
Personally I chose to fit my own and it took about 4 hours to complete the job. I bought my mine from Auto Trans Spares in Adelaide for about $150 with gaskets, and it's a TransGo Kit No. RE4R01A, but also suits the RE4R03A Trans. More info at
Also if your interested I have posted the circuit for my Manual lock up Converter at
Hope this is useful, good luck.

Thanks for your help, that's the sort of stuff I like on this forum.
I should have no problems with doing the work myself...I have a good mechanical history. I am very cautious though especially with new territory such as work associated with 4WD mods as I am from a marine & heavy industry background and I need advice from the wiser when in doubt.
cheers for now
