new transmission regrets.....

Sounds like you need to do some more of Step #2 from above! Be glad they found it now, and not on the side of the road.

 

Dave you need to do #2 as well. Nothing in a 10 speed can be "flipped". Only in a 9 speed can 8th and 9th be turned around.

 

You sure? A 15 speed is a 10 with another auxiliary section, and you can turn those around.

 

True a 15 speed is a 10 but the 5 extra gears are in the low side.

 

Just a word of advice, what ever gear that needs to be replaced you need the also replace the gear thats running with it.

 

Yes, ratio-wise, they are; but both are 5 speed main boxes. The 10 has 2 speed aux, the 15 a 3 speed.

 

To make a direct drive into an overdrive or a overdrive into a double overdrive is done in the main gear box. A 9speed is the only trans that this can be done in. Nothing is changed in the aux. box.

 

Let me correct myself a bit after some refreshing via eaton. A 15 is cousins with the 7,8,and 9 LL's. The 10's are related more to the 9,13, and 18. Has to do with the size of the deep reduction gears, the aux is vastly different.

I know this, my point is the main boxes are very similar across the whole RT line.
