Definitely using .75 in the calculations, that's of the first things I checked. All the other shift points seem to be normal, it's just the TC lockup not happening. Trying to isolate every external possibility before dropping the pan. If I do that I'll just do new solenoids and a sift kit just...
Have a 94 xj with 4.0/AW4 and since I did 1-ton swap the torque converter doesn't seem to lock-up. Per every calculator I've used I should be doing about 2300 rpm at 65 with 37/5.13, but I'm doing about 2650-2700 rpm. It get's into 4th but the TC doesn't seem to lockup.

I know a few people have swapped various bolts on their 4.0 and AW4 to studs. I'm looking to do a few myself and want to see what others have used and confirm specs/part#'s. Looking for the following:
4.0 ARP rocker studs for HS rockers
4.0 ARP valve cover studs
AW4 ARP pan studs
Thanks
