1987Bama Posted June 13, 2010 Share Posted June 13, 2010 I am looking at purchasing a really nice 1987 Pathfinder 4x4.It has the 3 speed automatic.Owner states the vehicle runs and drives great with no poblems.But tklls me the tranny indicator light is on on the dash board and it is normal.If it goes off,means the transmision is to hot. Is the correct?The vehicle is 3 hours away and before I waste my time,I would like to have more info on this light and the 3 speed transmission.Is this tranny better or worse than th 4 speed automatic thanks alot guys. as you can tell,this will be my first pathfinder Link to comment Share on other sites More sharing options...
Tungsten Posted June 13, 2010 Share Posted June 13, 2010 Its supposed to stay OFF and go ON when the transmission is too hot and the 3 speed is fine. Link to comment Share on other sites More sharing options...
ahardb0dy Posted June 13, 2010 Share Posted June 13, 2010 (edited) The early automatics (at least the one in my 87) did not have over drive, with the 4.62 gears that my 87 Hardbody had and with the stock 31's the engine would rev around 4000 RPM at 60 MPH, so consider that, I had 35's on my trucks so it reved high all the time, no OD was a bitch. Oh, My tranny lasted 130K miles before the first rebuild than I had it rebuilt about every 2 years after that, it's expensive to have rebuilt too around $2k each time !! I don't recall ever seeing a tranny light that came on when it got hot and I used to run in deep soft sand all the time on the beach back home, after the first rebuild the trans shop did install a external tranny cooler too.

1987Bama Posted June 13, 2010 Author Share Posted June 13, 2010 thanks guys. he is telling me the light is on all the time and would only go off if it ever got hot...which he says its never went off so it hasn't got to hot. i kinda thought he had that backwards anyway. and it has a new set of 31's on it so i am not sur i want to be driving 60mph and rev'ing 4k.wow.

ahardb0dy Posted June 13, 2010 Share Posted June 13, 2010 see if it has OD, it's possible depending on the month it was made maybe it had a later transmission in it. Link to comment Share on other sites More sharing options...

GrimGreg Posted June 14, 2010 Share Posted June 14, 2010 It is a trouble light, it comes on when the tranny is hot or when the tranny ECU has a code stored AFAIK. Link to comment Share on other sites More sharing options...
ahardb0dy Posted June 14, 2010 Share Posted June 14, 2010 if it is a past code see if the owner will let you try to clear it before buying it, if the light goes off take it for a test drive and see if it stays off. Link to comment Share on other sites More sharing options...

Tungsten Posted June 14, 2010 Share Posted June 14, 2010 FYI 3000-4000 rpm when cruising is fine, that is the power band. This engine wants to rev high to stay powerful and it has no adverse effect on anything. Link to comment Share on other sites More sharing options...

adamzan Posted June 18, 2010 Share Posted June 18, 2010 Does it actually rev at 4 grand going 60mph though? That is retarded if it does. Link to comment Share on other sites More sharing options...
