Change gear pattern?

I believe to change the shift pattern the entire gearbix would have to be rebuilt, to move the gears around... If it is even possible.

 

Pretty sure you would need a whole different gearbox,and I can about guarantee it's cheaper to get a different tyranny with shift pattern you want than to have somebody trying to switch stuff around.

 

I did the same swap with an 18 speed I had to replace the shift top or top plate whatever you want to call it. Otherwise it would have had a funky shift pattern

 

I like that rto 10, big hole against the dash pattern.
Think it would make the 5-6 upshift better..

 

There's 2 different shift bar styles typically used on Eatons. One uses a bellcrank-style link on the leftmost rail in order to reverse the direction of the shift fork. That gives you top gear to the back vs at the dash.

 

Also, any Eaton manual transmission I've had opened up, the 1st/R fork had a detent in it. Never had an auto transmision apart so not sure if they have the same fork or not.

 

RTOX denotes a Road Ranger, Twin Counter Shafts, O/D ( in the front box ) with a top plate that has the shift pattern you desire. The top plate would have to be replaced.
Springs and balls are under the shift tower held on by four bolts.
The first and reverse shift rail yoke has its own detent requiringing a little extra pressure to pull the lever from 2/7, 3/8 neutral to the left. If that is not working you need to take it back for warranty.
That repair most likely requires pulling the top plate. That can be done in some trucks but not many.

 

Drove an 8 sp. RTO years ago, it actually is a very good pattern. At one time they were very common in the construction/dump truck business, been away from one of those nearly 20 yrs and I still miss using those.
