A4ld RPM Shift Points,Flush
My 87 Ranger 2.9 had a delay in shift from first to second gear.I ran Seafoam trans tune thru it,changed the filter and flushed the fluid.After about a hundred miles the vehicle began shifting correctly again...or at least it's shifting as it was before the problem.I'm posting this thread to get some input on two issue 1)At slow acceleration the vehicle is shifting from 1-2 at 2000 rpm,from 2-3 at 2300 rpm and from 3-OD at 2300 rpm.Once I am in 3rd gear it will cruise at 1500 rpm,but starting from being stopped it will not shift out of 1st till I hit 2000 rpm and this seems too high.
2)Before I changed the fluid some particles of dark material would come off the dipstick when I checked the fluid level.After the flush there is much more of these particles.Whats going on here?
I don't think I did the flush correctly.Of all the info i've read on the Net,none of it talked about shifting thru the gears so I left it in Park.I now suppose that if you don't flush 2-3 quarts thru each circuit you're not getting a complete flush.
What do you think?
