Hello, im new here. Just picked up a 03 cclb 147k. Head studs egr delete new oil cooler and injectors. I have the old style sct livewire 9600. Was tunning ag street econo tune last night. Got in it pretty hard and it felt like the trans slipped between 3 and 4. Dropped into fourth hard and was fine after that. I put it back on stock and now if i ease into the throttle slowly the trans slips 3 to 4 but if i hammer down the throttle it shifts smooth. Not sure if i messed something up or what. Any ideas ?

Anyone ? Anything i can check too see if theres anything wrong with it ? Fluid is clean and does not smell burnt at all.

When you change tunes it takes time for the adaptive software in the transmission controller to adapt to the new settings. It's normal, as long as the shifts improve within the first couple shifts.

Thanks. I returned it too the stock tune and it seems to be improving. But it did slip one more time after about 10 minutes of driving. Not as bad as the first time. Any upgrades to the stock tranny that are recomended to fix any common issues ?

I don't have any mods to recommend.
