Hello,
I am looking to try and figure out what is going on with my transmission, mainly my TCC I believe. When I bring my speed up to aprox 65 km/hr and then begin to coast down to aprox 60 km/hr the truck kinda jerks a bit, like the torque converter can't decide if it should unlock or not. I have a 427 SBC with an LS1 B computer, a 4L65E monster transmission with an 1800-2000 stall, and currently 3.73 gears in the rear end. A guy from work told me to gently tap the break and see if it goes away, he said that tapping the break should disengage the torque converter electronically....can anyone verify this? Are there any small tweaks I can do in some tuning parameters to try and rectify this issue? I believe I have attached my current tuning file. Please let me know if the attachment did not work. Any help is greatly appreciated.
Thank you guys,
Jordan.
