how to convert trans to split the top side

I think only the 9 speeds can be converted not the 10 speed but am happy to be proven wrong

 

some of the 9spds are convertable to 13spd but not a 10 spd

 

not 10 sp.

really 9 sp may be converted to 13 sp changing cover and input shaft, but belive me it is easy to find 18 on JY

 

ouh, not cover only.... more internals))) LOL

 

On a 9 speed you change the back section of the gearbox, the internals of the main box stays the same. Haven't seen it done on a 10 speed.

 

9 speed transmissions were with other input shafts so you cnt use it on newer truck. As I've understood idea to purchase old 9 sp (cheap), coonvert it to 18 sp (using back section from toasted 18 sp), remove 10 sp and fit 18 зp (mad of 9sp).

 

I have not seen an RT or RTLO series transmission that doesn't have a 2"x 10 spline input shaft, on one that is different is RTLO22918 which uses a 2"x 14 spline shaft.

There is no way just to change airlines to allow a 9 spd to work as a 13 spd, there has to be splitter mechanism added to the back of the main case.

 

If you have a 10speed, then that's it!!

 

And that's it! Thanks for keeping it accurate!
