Transmission service urgent message came up. Low oil pressure warning also came on . Stopped car , shut off engine and checked engine oil level , and it was perfect in safe area. Restarted car oil warning went out and transmission seemed normal . Then suddenly transmission while in drive will not down shift either automatically or manually. Any ideas?
will not up-shift from 2d to 3d normally, but if I can really slowly increase the speed sometimes it will shift and then be OK till I have to stop for something. Later I learned to pull over, shut off engine, restart and then do the slow sneak up. Dealer said "new xmsn for $4710 and new control computer for $700"
