P.W.T.Engineering Posted April 10, 2017 Share Posted April 10, 2017 As it says I have an RTO613 yes a little baby 13 spd but the shift pattern is not what I remembered I read up and everything says 3+5+5 But it doesn't work I get overlap I'm currently using a 5+3+5 and that works does this mean someone has done something inside this box to enhance gearing ??

j hancock Posted April 10, 2017 Share Posted April 10, 2017 Link for a RT-613 and RTO-613 transmission manual may be helpful. Page 5 and 6 have the ratios and the shift pattern. Includes a note that the 7/12 and 8/13 hole is reversed positioned on the RTO. http://discounttrucktransmissions.com/wp-content/uploads/56_fuller-RT-613-transmission-service-manual.pdf Quote JimIt doesn't cost anything to pay attention.

P.W.T.Engineering Posted April 13, 2017 Author Share Posted April 13, 2017 Ya that's typical with an overdrive hence the rto instead of the rt it's a w pattern instead of the H pattern but the book shows a 3+5+5 pattern and it just doesn't work any body else get this with their rto xx13?

VT Mack Posted April 13, 2017 Share Posted April 13, 2017 Wow I thought my RTOO-9513 was different Quote Link to comment https://www.bigmacktrucks.com/topic/49490-rto613-shift-pattern/#findComment-367291 Share on other sites More sharing options...
VT Mack Posted April 13, 2017 Share Posted April 13, 2017 The RTO 9513 is a standard H and you split the gears on the high side with low down to the left Quote Link to comment https://www.bigmacktrucks.com/topic/49490-rto613-shift-pattern/#findComment-367293 Share on other sites More sharing options...

P.W.T.Engineering Posted April 24, 2017 Author Share Posted April 24, 2017 We have determined that it is in fact anot rto613 but the fact also remains that the overlap is between intermediate and direct if there are any old school guys that can explain this I'd be glad to hear why this is Quote Link to comment https://www.bigmacktrucks.com/topic/49490-rto613-shift-pattern/#findComment-368265 Share on other sites More sharing options...
j hancock Posted April 24, 2017 Share Posted April 24, 2017 Do you know what the trans. number is from the case stamping or tag? Knowing what it started life as will help.

P.W.T.Engineering Posted April 25, 2017 Author Share Posted April 25, 2017 Talked to my buddy Allen at the gear shop in Phoenix he said airlines are not right and I'm splitting the upper half instead of the lower half It works but it's weird Quote Link to comment https://www.bigmacktrucks.com/topic/49490-rto613-shift-pattern/#findComment-368321 Share on other sites More sharing options...
