Quick question: is 130 psi good compression on a 5.9 V8 with about 205,000 miles (330,000 kms) on it?

Unless you've flushed it before, I don't recommend flushing the tranny. Others will also most likely chime in with the same advice. Filter and fluid change should be enough, unless you don't want her to run well anymore

Don't flush change your filter and reuse your trans fluid if it still looks good.

On topic arranged to get a 231 and sye kit for Christmas. That means one more trip to Uwharrie for thanksgiving and the I'm swapping the Rigs 242 in to my DD in place of a bad 249!

Was that tested warm or cold? If that's cold, it's probably fine, but you should re-test with the engine at least somewhat warm for a more accurate reading. If that was warm, then that engine is definitely somewhat worn, although it's not shot. Also, try doing the test, then adding a teaspoon of oil to each cylinder and doing it again. If it goes up noticeably, the rings are worn, if it doesn't, it's valves that aren't sealing perfectly.

Also, make sure you're doing the test with all 8 spark plugs out, hold the throttle wide open while cranking, and make sure you hear it spin at least 4 times for each cylinder.

Factory specs is 180psi for these, and somehow, mine still tests 170 - 175 on all 8 cylinders, so I'd be a little surprised if yours is actually that worn after 205k (mine has 143k, last test was done at 136k).

The reason I was thinking flush is because I'm not sure it has ATF+4 in it. I wanted to fill it with the correct fluid. What is problem(s) with flush?

Power flushes can occasionally cause issues if there's any clutch material stuck somewhere in the trans and it gets dislodged and re-stuck somewhere more important (valve body). However, a cooler line flush is safe to do. Once you've done your pan drop and filter change, disconnect the trans cooler feed line, run it into a bucket, start the Jeep. Place it in Neutral, fluid should start flowing. Have a helper watch the level in the bucket. Once 2 - 3 quarts have been pumped out, place it in park or shut it off, the fluid flow will stop. Add 2 - 3 quarts of fluid to the trans and repeat. If you want to get a full flush, it'll probably take about 12 quarts (3 gallons) run through this way, assuming you started after a pan drop.

Thanks for your response. The cooler line flush method is what I was thinking to use. I suppose the power flush method still uses cooling line for access but uses an external pump to push the fluid vice the engine/tranny pump doing the work?

when i did mine getting them out wasnt to bad. i used an air hammer and a sledge just back and forth and they punched out, make sure you get the snap rings off. and i cut the balljoints to get the knuckle out of the way and had room to worrk then took some sand paper and cleaned everything up a coat of black spray paint and it all went back in a whole lot easier

I'm guessing you take the brake off? Have to take axle shaft out?
