I've done a lot of searching and reading but can't find a more or less updated and definitive guide. Hoping that we can come up with a consolidated guide to swap from an Auto transmission to a Manual transmission. I'd like to keep this first part geared towards non-paid programs(Universal Patcher), stock vehicles, and OS bins posted here. If you can reiterate why this change needs made and what the setting is under in Universal Patcher I'll add it to a list.
What order or other changes need to be made to the Calibrations for a manual swap? I see talk of these snippets:
- take a 5.3 auto trans tune and do the following[disable trans diag, disable torque mgmt, copy idle speeds, raise base airflow] -bobcratchet555
- One of the challenges I've noticed with a custom manual 5.3 flash is the Deceleration Fuel Cutoff (DFCO) parameters. Automatic transmission vs. manual transmission requires very different DFCO parameters -dave w
- [RPM limiting to 1600] i have had exactly the same experience with that tune, or any time i try to segment swap a 5.3 with manual -bobcratchet555
- decel stall could be a combo of air and timing. Idle and low RPM timing control is setup pretty different from auto to manual. -Skinny Pedal
- Edit the 4.8 to 5.3 and scale the idle airflows. Use the 5.3 VE. Use what ever timing you like. Keep all the parts associated with the manual. Leave the throttle cracker and follower alone. Do not do an engine segment swap or you will write over the important manual parts. -Skinny Pedal
Here's where I stand currently with my swap '5.3L DBW NV3500 4wd(manual t-case) OS 12593058':
- Read Entire PCM(or download) [A]2003 Silverado 5.3L DBW 4l60e 4wd OS 12593058 bin
- Read Entire PCM(or download) [B]2003 Sierra 4.8L DBW NV3500 2wd OS 12593058 bin
- Deleted VATS
- Segment swapped Trans Cal and Diag from [A] to [B] - this is wrong?
- {?Manual changes?}
