[QUOTE="tnutcher, post: 1469561, member: 28594"] Hey guys 1st post, thanks for all the great info, been enjoying reading up and learning a lot! Also threw this up on .org but I'm looking for some help on an issue. Bought my truck with a Banks 6 gun and pulled it and installed the mini max with hd300 tune and s1l and loved it. Started fighting the 3-5 shift flair for a while and got so bad shifting that I finally rebuilt the transmission: Rebuild kit New Stock solenoids Bonded piston kit Power pack clutches (with milled plates to fit more in each pack) Pdq converter Trans go shift kit $4700 installed Put truck to stock before taking it to get rebuild, and it shifted well afterward. Threw the hd300 and s1l back on and from 4th locked it would run out, unlock, upshift to 5th, then relock. With the new converter the locks are very firm and the truck would clunk unlocked and rev up clunk locked again. Very annoying. Ended up running s2l to compensate. Started getting a flair in the 3-5 shift again occasionally. Reading more about the HS trans files I wanted to try custom tuning to tighten and firm the shifts up. Bought tunes from Byall Style with a 3rd gear lock and I'm getting the same unlock-upshift-relock sequence in between 3,4 and 4,5. Really jerks the truck around and revs the motor high. Talked to Jesse and he was saying neither his tune nor the HS s1 trans files are supposed to unlock between upshifts. I've been running the s2 schedule that I increased the firmness on and bumped the line pressure 20% and it's been running great, no flairs and good firm shifts, but I do miss the 4th gear lock. Jesse was thinking it might have been something hard parts in the build causing it to unlock. Anyone have any insight into why it would unlock before upshift on 2 completely different tunes that call for continued locking. Or things I can check in my MCC files, I've imported a s1 file to check out but haven't found anything yet. Not sure if it's a hard parts or a tuning issue. Trans guy is saying tuning, tuners are saying trans. Thanks in advance guys! TNutcher Sent from my SM-G900T using Tapatalk [/QUOTE]
