Message: [QUOTE="Dan, post: 776840, member: 12188"] im just going to jump right in!!! ok so i have been dabbling with mcc trying to control my 6r140 to produce constant, firm, precise shifts every time.. I'm having mixed success, if i try to tighten up my shift timing it seems to flair between shift, so i leave that alone and mess with shift pressures.. with lots of shift pressure i manage to get a firm shift but it seems to have a mind of its own... quite difficult to dial in.. now the icing on the cake is, randomly, (typically the 3-4th shift) will disengage 3rd, will not grab 4th and rpms skyrocket to rev limiter... then after around 3-5 seconds it'll grab 4th and continue on.. (I'm sure if you have experienced this you will know exactly what I'm talking about) so heres what I'm stabbing at with this: i am looking if anyone knows of anything to control this trans in a very precise manner... i contacted "Powertrain Control Solutions" and they told me that they are working on something but didn't give me any real details about what they are up to, or any eta dates.. im sure ats is working on a copilot for the 6r but as for right now im looking to know if anyone can give me any insight? tuning programs that can control the 6r better than mcc? any help is appreciated!
