Topic: new marlin built w56b issue

[keycw]

took it out and ran it in the early Louisiana heat.  hit highway speeds of 75mph, crawled through traffic, shifted through all gears, and no problems.  I put right around 150 miles and did not get a pop out of 2nd, or any other issues for that matter.  I was able to speak with marlin yesterday and talk about it and they said they were happy but still clueless.  I plan to take a 2 hour trip this weekend in it, if there are still any issues they should have come up by now I would think.  im not contributing the fix to the gear oil, but I will say there is a noticeable difference in the shifts between regular off the shelf 90 weight and the redline mt90.  heres some pic from running through a sugar cane field the other day, because its the south and thats what we have

Hi guys.  Maybe I can shed a little light on this, and I apologize to keycw if I wasn't very clear about it when we were on the phone.  So the fact is these are rebuilt transmissions.  That means utilizing used factory gear sets, shafts and ect, with new bearings, synchros and seals.  The builder does a super thorough inspection of the parts (most of our specs of what we call within spec or usable is more strict than Toyota).  However he cant always catch everything.  These transmissions have a slider that goes over the hub and attaches to the fork.  Sometimes there is a microscopic metal transfer from an old slider on to the hub or vise versa.  This cant be seen by the naked eye (or with our builders maginfying glasses) but will cause just enough of a resistance in the slider moving the hub so cause it to not engage properly. When it was torn apart and inspected there was nothing visibly wrong, the possibility metal transfer could be the only thing causing the problem.  The hub slider and fork were replaced, eliminating that possibility.   Hope that helps.
