It was time to do a filter & fluid change on the 03. Very pleased with what I have found. The filters and fluid haven't been changed since Dec 2017, before the truck started doing it's fastest runs yet at full weight. The trans fluild looked so good, didn't even change it out. Just topped it off with new trans fluid.
This is the modded Sharadon trans with the Smart Tech OD hub and the increased line pressure spring in the trans fluid pump. This is the same trans that did a 12.7/12.8 @ 105 to109mph at PBIR and Orlando Speed World. Did a 12.6 at Gainesville raceway with a throttle body shut down at the 1000' mark. It also did several boost test hits as well. The 03 was in full street trim with 22" SRT10 wheels at the weight of 5752lbs. Never changed the filters or trans fluid after putting the 03 back to stock. Just left the modded sharadon trans in it with the oem tc. Been driving it daily back and forth to work with various trips.

PS. Never do a wot overdrive to 2nd prime down shift. That's what destroys the od clutches in this trans.
