I have been driving my LS 400 for about 11 trouble free yrs. 8-10,000 miles ago it began shifting late when cold. The dealer said the transmission filter needed to be changed so I had that done. No change in the shifting. Could this be a computer problem? Thanks

No not a computer problem. I would take to a transmission shop and have them check.

I had a problem, mostly noticeable when shifting at interstate speeds where it would rumble for several seconds before shifting on my 98...turned out to be the transmission mounts
