    Hi Mount Manifold.

    Ah cool, I think I stopped buying Zoom around the 200 mark, cheeky buggers were running exactly the same cars and stories in another mag.

    I will have to hunt that issue down.

    Looks like you know what you are doing by those welds, look forward to seeing the end product.

    Rb25De Stalls When Put Into Reverse Or Drive

    in Drivetrain and transmission

    Posted · Edited by FJ RB25

    Not raining on my parade at all GTS boy, like I said I am no expert on Auto's thanks for the info , always willing and open to people who know more than I, after all that's how we learn from folk that know more than us.

    I have a question though, if stall is operated or initiated by the TCU ( transmission control unit) why do people go and purchase a higher stall converter for their car when they can just dial in a higher stall through the TCU ?

    In saying that it would seem silly for all those people that go and buy a high stall converter for no reason.

    The way it was explained to me was that if you have a 2500 rpm stall then the two halves and the stator would not be locked up and give you positive drive till 2500 rpm.

    Is this correct?

    Always willing to learn from someone with more knowledge.

    Hey UCD

    When even trying to diagnose a problem it is often a good place to start at what has been changed as in majority of cases this is a good place to start ( not broke before changing anything but now is after changing something )

    You are saying that the trans oil has been changed but you were not present when the oil was changed ( is this correct ?)

    And

    You had a problem with a coil ( did you test the car after you changed the coil) ?

    The problem you are describing sounds like a converter lock up clutch staying locked up ( google how a converter works and you will see some vids on YouTube)

    Basically a converter clutch will lock up at a certain rpm, I.e. 2500 rpm stall = lock up clutch will lock up at 2500 rpm

    If your lock up is locked up from the get go then you will stall the engine either in reverse or drive.

    If the engine is standard then the converter should lock up around 2000 rpm I think.

    Not sure how you could test if it is the converter but I would imagine that if the engine was kept above the converter stall it should run. I.e if you took the car to 2000rpm and changed gear each time above 2000rpm or stall then it shouldn't stall in theory.

    Now I have had Eff all to do with auto,s but that is what I have self learnt from the net and YouTube, reading books, not having a dig here but look at the net or ring a auto trans shop.

    All the best mate, oh and before anyone else mentions

    Stick a turbo on that De
