shifting issue can it be the tune??? Mustang LS swap 6.0 vortech with 4l65e PSI harness with truck PCM just flash
Question having an issue with my 4l65e shifting as it started with the vent tube being disconnected causing smoke coming out at WOT. Now that I have found the hose that goes connected to the vent tube tranny doesn’t smoke problem solve there. Car is not shifting gears like it did seem like it’s on over drive or haul bottom. I can only assume maybe since I connected the hose its holds more pressure over the vent tube just being open. Ill check the converter locks or unlocks could this be it? or Maybe I need a correct data tune in my PCM for the tranny not sure what’s on there right now. I do know it has the wrong gearing and tire size to what I have. But keep in mind the car shift before fine now 2 shifts at 3rpm third won’t unless I release gas then let the RPM go down or it might but the RPM just goes up to passing 4rpm. Hope I can get some pointers on this issue if it’s the pcm can anyone referred me to a sponsor or anyone that can tune my PCM correctly.
