So a while back I read somewhere on here about how having a G56 will change the gear reduction. Basically what was stated is that if you have a G56 with 3.42 and a 68RFE with 3.42 the G56 will reduce your gearing to where it's more like drive a 68RFE that has 3.73's. My previous truck started with 3.42's and I swapped to 3.73 for better towing. It was an auto. Even with 35's it towed much better with the new gearing. New truck is an 18 3500 bone stock G56. Can anyone that knows about this lend me more insight. I've done Google searches looking for any more info as well as try to find the thread but it was quite awhile back I read it.
