Trans slip ? Allison 04.5
My Edge/Attitude in level 1, displayed up to 2%, fluctuating from 0 to 2%, trans slip last weekend on a trip. GVW was about 21000#, gooseneck and atv,s. The only time slip was indicated was on I-75 Jellico hill in N. Tn. in overdrive @ about 65MPH. This hill I think is about a 6% grade. Last year in Colorado no slip was observed on any grade and some were steep!
Any thoughts? Is this an acceptable amount of slippage?? I think Gm has noted up to 50 RPM slippage in OD is a rule of thumb, but does this apply to the Allison?? 2 to 2.3 % would be close to 50 RPM.
