Hi everyone
So few days ago I dropped the transmission pan and changed the fluid/filter (dexron vi, AC/Delco filter). The old fluid was not burnt, just a dark red. No shavings in the pan. Afterwards I drove it around to make sure everything was kosher. It drove great, no slips. Even under WOT it shifted perfectly. When I got home I noticed the fluid level was just a hair low, so I put in some more. I assumed I was good, so I left it alone after that and called it a day.
Today on my way in to town the transmission would not shift past second gear. It would just keep revving up in second gear, like it didn't even attempt to change into 3rd. It didn't slip or feel like neutral or anything like that. I pulled over and shut the truck off, restarted it, and continued to drive. It went into 3rd (and 4th) good (although a bit softer than normal), but when I got home I realized that the trans fluid was a bit too high so I drained out just a bit (1/2 quart?), the level is perfect now and it is shifting perfectly at all speeds and under all types of acceleration. No slips at all, even under WOT. I have had this happen before after a car wash (with the underbody wash), but after a minute or two it fixed itself. This makes me wonder if there is something electrical going on.
Is this something I need to worry about? Do I need to start saving for a trans? It is an '01 Suburban with 117k miles on it. The thing that concerns me is that the previous owner (my uncle, who bought it new in '01) used it to tow their camper and go on longer trips down south. I am hoping that the transmission isn't going to start giving me issues, I need this truck to be reliable enough to take it across the country if need be.
Any thoughts on this would be appreciated!
