Its a 7.4 from factory. The vin and all the numbers check out. All those manuals only go to 1998. My truck is a 2000
Assuming you have a 4L80E, it sound like your forward drum has deep grooves cut into it's inner diameter where the input shaft sealing rings are located. One of the most common problems on those units. These grooves allow apply fluid to blow by/bleed out instead of going to the apply piston. The apply piston can't fully compress your clutch pack until you basically floor it to get the pressure high enough to offset the bleed/leak in the circuit.@BeXtreme
Thank you. After i posted my last reply i refreshed my page and saw your reply.
The transmission just shifts sporadically. Somtimes it shifts fine but othertimes it just wont. The only consistency i have found is at wide open throttle. It seems to always shift when and where it should if my foot is on the floor. Otherwise somtime it just wont shift or tries to shift to early and bogs down. But usually it will just shift between 3,500 and 4,000 rpm (not accelerating and no load) and shifts hard when it does. I am assuming its an electrical issue or sensor of some kind causing this. Maybe i am barking up the wrong tree and its just a bad transmission.

No, it should be displaying live, real time data...If the scanner is functioning normally on your wife's vehicle, perhaps there's something in/with your truck impeding comms to the scan tool. I have two 2000s era Chevy trucks and both render live data as expected using my TECH2 and SnapOn scanners.While I wait to find time to investigate the transmission issues further. I am still curious what is going on with my obd2 reader. I have never had one before, so I am not familiar with what is normal behavior or not. I know some of the live data is wrong (rpm for example), so I worry what else might be wrong. Also, is it normal for the live data to only update once every 30 seconds to a minute? After getting the obd2 tool, I tried it on my wife’s vehicle (only other vehicle we have new enough to have an obd2 port) and the live data was… live. It updated instantly and I could see everything that was happening as it happened. Is that just how these trucks are (slow) or is it a compatibility issue with my reader and the truck or is it a symptom of something going bad with the truck computer. Using google, the only thing I found was on a Toyota 4 runner forum, but the problem was specific to his reader truck set up so nut much help for me.
TLDR: is it normal for the live obd2 data to be really slow on these trucks?
