Hello,
New member, and first time poster here! I have a strange set of issues going on with my '95 that I wanted to share and get some opinions on from anyone that cares to offer some feedback. I've been a long time viewer of these forums/threads, and I've found a number of posts/threads that partially get at the issues I'm seeing, but can't find any that totally nail it. Caveat: I'm not very mechanically inclined, but just looking for potential or probable causes for what I'm seeing (or things that I should try) that I can check or have inspected.
My ride: '95 Explorer XLT, 4dr, 4WD (4.0L engine), 242,000 miles
The situation:
For background, I've done trans rebuild (~140K miles), and a replacement with scrapyard tranny (done at ~180K miles, with a tranny that had ~88K on it). Also had the transfer case replaced with a reman unit at ~160K.
About 6 weeks ago, I had some routine maint done: plugs/wires replaced, coolant flushed, and tranny fluid/filter changed (pan dropped/cleaned, etc.). Fluid was still generally pink, but just starting to get that brown tint to it. Mechanic said the pan wasn't bad (no sludge, metal shavings, etc.).
Since that time, I've had an issue that only occurs at highway speeds, and only until the car is warmed up: When I get on to the highway (after about 3 miles from my house), and get up to ~65+, it feels like it is repeatedly downshifting (RPMs increase suddenly by about 700, then drop back to prior level after a second or two). It will do this for about 5 minutes, then it stops and settles back to the lower, typical RPM and shifts perfectly smoothly for the rest of the trip no matter how long. Once it gets past that initial issue, you couldn't ask for it to work any better or more smoothly.
I did have one other thing happen last week - just as I was slowing down to exit a highway, the o/d on/off light flashed about 4-5 times, and then stopped (and hasn't happened since). Also, the 4WD/4WD Low light also did the same thing the next time I drove it. They haven't appeared since. The o/d light flashing was the precursor to my first transmission failure, but it was on constantly in that case, so this seems different.
In looking under the hood two weeks ago, I did notice that the hose connecting the air intake to the oil fille next was unplugged at the air intake (maybe was knocked out when they were replacing the plugs/wires). I plugged it back on to the intake, and also replaced the dirty air filter and cleaned the MAF per suggestions I had seen here, but still no change.
Anyone have any suggestions as to what I might try next? I drive this car about 65 miles/day, and would love to keep it rolling! I can't figure out if this is really a transmisson end of life kind of issue, or if it is something being triggered by some other root cause. Any feedback would be much appreciated.
Thanks, and love the forum!
