random hard shifting issues
97 F-250 7.3L E4OD 2wd stock. tranny was rebuilt around 75,000 has 164,500 now
trans filter has been replaced along with about 14 quarts of fluid. i am also running two trans cooler one a tube and fin type the other is a large plate fin. I was having a temp issue and deleted the radiator from the loop. trans temp is now 165 on a 100*+ day in stop and go traffic and drops to 155 on highway. now on to the problem
there are times when im driving when the truck would shift really hard and other times when it would work the way it should. it could happen when it starts in the morning and goes away a few miles down the road or after a 120 mile trip to my moms house. sometimes it will stay for a few miles and sometimes it will stay for two weeks or be gone for two weeks.
when everything is working right when i shift into drive the is about a 1 sec delay and a soft engagement. when it is shifting hard the truck jumps as soon as its in drive. if i accelerate slowly i can lessen the harshness but if the TC locks in third before it hits OD it doesn't matter. if i floor it between 1st and 2nd it is not noticable but when i let off it will slam the hardest into whetever gear it should be in.
EDIT: i did search but kept finding leaking tranny post
