    Default Manual to automatic transmission Gen 1 Pajero

    I am considering converting my Gen 1 pajero 4d56 tdi from manual to automatic transmission. A few mechanics I have talked to say this is doable but not recommended! What are the views of the experts?
    Any benefits or drawbacks.
    Regards

    Not many benefits apart from being able to drive with one leg and one arm.

    Slower acceleration, higher fuel consumption etc.

    Well considering the ammount of work that is required cost you better sell and get an auto one. I understand it can be problem while driving this ride on manual. If your ride requires automatic transmission which is not hydraulic but electricak then you have to change wiring ecu or add PCM etc....

    Thanks for replying.
    Acceleration is already not very good on manual transmission and fuel consumption is around 7.5-8km/l.
    How will auto transmission effect hill driving and off-roading?

    Selling is not an option right now because my ride is in a very good condition and finding a good Gen 1 with auto transmission would be quite difficult.

    It's consuming too much. You need to sort out the fueling / turbocharging before you go to fitting an auto.

    As a side note, it'll be easier to drive off road with an auto. Hilldriving, I'd prefer a manual.

    As it usually happens MITSU_MAN has pointed out the biggest advantage of the A/T, and that is the ability to cruise for hours on end without frying your 4D56.

    The auto is geared taller than the manual. So at highway speeds, the engine in the auto turns slower than the one in the manual. This reduces stress on the engine.

    Thanks a lot for putting in valuable information. The advantages appear to be
    Being able to cruise at motorway speeds.
    Advantage in offroading.
    And of course saving an arm and a leg, very useful while caught in traffic.

    The disadvantages seem to be
    Fuel consumption.
    Finding a mechanically sound auto gear.
    Cost.

    The biggest advantage to me is being able to cruise at 120 without damaging the engine. I have driven on motorway innumerable times without any problems but I take care not to keep the rpm above 3000 for long periods.

    Now the problem is finding a good auto at a reasonable price.

    does this mean that manual intercoolers have heating issues on the motorways.

    i am surprised. isnt this flawed engineering?

    Seeing as the rated top speed is ~130 km/h from the factory, I'd hardly call it flawed engineering...

    What is the idle cruising rpm and speed for 1 gen intercooler turbo 4d56td manual? Can u be as elaborate as possible? I mean where should the temperature needle be? Halfway? Or always below that? 1st gen has a line break in temperature needle on instrument cluster. What does that break in line mean?

    You're too kind. I haven't tackled these kinds of conversions, ever. You need a proper transmission dyno to troubleshoot these A/Ts

    Ideal is around 2k rpm. But that only nets you 72 km/h on a manual in 5th gear. 3000 rpm is 108 km/h, starting to get troublesome. 120 is 3300-3400 rpm. Honestly too much for sustained running.

    Temperature needle should stay around the bottom fifth of the gauge. Definitely in the lowest segment. My own 1UZ conversion stays below the lower segment line, or break.
