This has only happened one time -- I've never since parked the car in a location which would recreate the conditions under which this occurred. Car was parked nose down on an incline (not hugely steep, maybe between 5 and 8 percent), and I had rolled the front wheels over the asphalt pavement edge (a lip about 3 inches high I'd guess). Shifted into reverse, gave it some gas, and I got that slipping feeling as it tried to pull itself over the lip. It caught and I did get out, but it worried me, as you can imagine.
As far as I can tell, I have the late model 4L60E (99 tahoe 1500 4x4), which is original to the truck as far as I can tell. It has 119k miles on it, has never been used to tow (p.0 is original owner, that's what they told me, evidence supports that). I do not have evidence that the trans has been serviced (have records back to 2004 and 30k miles or so). Trans works fine except for aforementioned incident.
I've got an oes filter kit coming this week, and I'm planning to change the filter and change the fluid. Not planning to flush it. Is there anything I should do to prevent future slippage? Like an additive that would be safe to use, or would you not recommend that.
