Good info about the shifting. This is the slowest darn van to engage that I've ever driven. Put it in drive, wait 2 seconds for the soft clunk, then go. I always do that. But I bought it used at 50,000 so maybe the guy(s) who drove it 50,000 miles before me never waited. Well, now that I have this newly rebuilt tranny and torque converter, you better believe I'm pickier than ever making sure not to move until it engages. The one time I was in a hurry and I hit the gas too soon, it was a harsh "clunk" and "wham." I believe your mechanic 100 percent correct when he says doing that over and over can have a negative impact. But the better question is, why is this dang tranny so slow to engage? Annoying, especially when backing onto a busy road and having to sit there 2 seconds for full engagement. |
