Reverse will engage when fluid is cold, but once it's warm I have no reverse. I'm going to do a pan drop and change the transmission fluid and replace the filter. Then have a transmission shop look to see if it might be something like a solenoid. But if it's something major, I could easily continue to drive it around town without reverse. I've done it for a few weeks and haven't had a problem.
Has anyone driven their vehicle for a significant length of time without reverse gear? If the reverse can't be fixed, I'm wondering if I can just drive it until the forward gears start to fail. The forward gears are still shifting like new. I am only driving it 3k-5k miles a year as it's our "extra" vehicle. Has 255k miles but is still in excellent condition.
