Ok, I have a 18 JLUR (Automatic) with 37s and regeared to 4:88, love it. However I did it because we occasionally tow a 3000 lb trailer. 70% of towing is done on the rolling hill highways in Missouri, with the remainder being Colorado mountain highways, which we will be heading to this summer. Without the trailer and with the 4:88 gears this JLUR runs great, no complaints at all.
Today was first time towing after regearing. Could cruise easily 70+ mph and maintained speed However, at 70mph we were at 3200 rpm 6th gear. When it would down shift on hills, we would be around 4000-4300 rpms. Flat land, we'd be back between 2200-2400 rpms in 7th or 8th.
Tranny temp ranged between 195 & 216. Everything else appeared normal.
Question, is this normal rpm range when towing 3000lb trailer up hills or to high. Don't want to harm tranny.
