Re: Are smooth shifts bad for your tranny?
I had my 460le rebuilt in my tahoe and I thought it shifted to hard and I took it back to the shop and the mechanic checked it out and said it was fine and that it shifted firm because they had increased line pressure to engage the clutches better to keep the trans form prematurely dieing.
