    WOT shifting issues at track. twin turbo escalade

    2010 escalade twin turbo setup. I have an issue that is costing me alot at the track. It goes to nearly 6k rpm in third but doesn't shift to 4th instead it stays in 3rd and bounces timing down negative and drops RPM way down. Any ideas?

    would suspect its running off the safety shift tables.

    can you not apply the custom SD OS to this?

    looking again at your log you can see its trans TM ripping all the spark out as it tries to make the 3-4 shift.

    your trans file shows WOT shift RPM of 5200 or 5425 depending which table its referencing. but all the 100% TPS and 3-4 WOT shift speeds are like 139, 143km/h etc. its likely the car goes into TM because its reached its shift RPM point but is still 30% or more off its required speed to make the shift. get the 3-4 WOT speeds and RPM to correlate and it'll likely fix your problem

    Thanks for response. I will look into it and get back with results in the next few days.
