Hello, I have a 1994 GMC Suburban with 190,000 miles on the 5.7L engine w/automatic trans. It has been well maintained but I'm having a few problems. The first is with the transmission. Basically, it will not shift automatically from 1st to 2nd. The RPM will actually redline if you stay on the gas. When I take off of the gas at higher RPM's and then press it again, it will shift into 2nd gear. No problem with shifting from 2nd to 3rd, etc. The truck doesn't have any acceleration problems and when I treat it like a manual by taking off gas & pressing again, it's pretty much all good. Any suggestions or has anyone had a similar problem?
The second issue is since I bought the truck used @ 4 years ago the oil pressure gauge never reads normal, always very low once warmed up a little. No knocking or any other problem with acceleration etc. It just has me concerned. Oil/filter changed regularly and a once or twice I even did an oil flush on it when changing the oil. Nothing changes, remaines an issue. Any suggestions on this?
have the same problem?
