diesel Posted October 12, 2011 Share Posted October 12, 2011 I have an 350 hp E7/8LL in my grain truck. The axle ratio is 4.42. I am looking for a different tranny to install, since I dont like how the low side of the 8LL has to be short shifted and the high side is long legged. Can a splitter be added to this 8LL and make it a 12 speed? If not, what tranny would be a good candidate to swap in this truck? Thanks.

slpwlker Posted October 12, 2011 Share Posted October 12, 2011 Are you looking for something with a deep reduction and less top end? Could try a 15 speed it is a 10 with a deep reduction. but idk if a 350 has enough to run it as they do have real long legs. I have seen in a block carrier I hauled a few years ago a 13 speed but it had a deep reduction. Never seen another one like it. If I remember right it had the same handle as the 8ll just think the low 3 where deep and the rest where on the highside. reminded me of a round knob 13 Quote Link to comment Share on other sites More sharing options...
David Posted October 12, 2011 Share Posted October 12, 2011 Get the numbers off the trans so we can tell exactly what we're dealing with. Quote Link to comment Share on other sites More sharing options...
MACKS Posted October 12, 2011 Share Posted October 12, 2011 Twelve speed over drive would be my choice,that's what I have now and also had in my last truck,never had a problem with ether one,also works great with a 350. Quote Link to comment Share on other sites More sharing options...
