Mack R series 18 speed

[sambino918]

Is there an 18 speed transmission mod available for the mack r series? The 13 speed honestly has way too long of a 13th gear and I keep having issues pulling heavier trailers with how far apart the gears are even in the 13 speed.

I thought there was one, just couldn't seem to see it in searches. That should help out immensely with my truck.

That's not so much a 13 vs 18-speed thing, rather a final-drive issue. The 13-speed and 18-speeds are usually the same in the high range (4-8), it's only in the low-range where the 18-speed has the hi-low split on L-4 for better heavy load off-the-line performance

I've been driving with the 18 in the truck, and honestly the gearing is way better, just having more gears has seriously helped because it seems like with the 18 there are more gears higher up in the speed range vs the 13 which had 13th from about 45 mph and up.
I have the same final drive ratio between the 13 and 18, but the difference is in the gears themselves. The 13 speed for some reason had every gear up until about 11th have way too high of a ratio, and then the last 2 gears had about the same ratio, whereas the 18 speed has the gear spaced more consistently.

I use the E-f 918B with a DD 12v71 turbod- 525-550hp version, and the truck is literally a god of road.
