I installed a fresh 6l90 with a circle d stall 2600 to 2800 .
Few issues and main is the odd trans slip not tcc slip but trans slip . In the log it will shift into 3rd and at start of shift the trans slip will jump then settle back down . After that it happens again and fells like it shifts 3rd twice . I am so lost and this is drivng me crazy as no one has a answer .
