1986 F250 with 1989 7.3 n/a & C6 from an 89 E350 swapped in. Standard sized transmission pan.
Just did a fluid and filter change. I Rowed through all of the gears, drained the oil, put new pan gasket and filter in, Put 8 quarts of MECRON in.
I row through each gear and sit in it for a good 10 seconds & then I’m pulling my dipstick to check my fluid while hot idling in park.
Problem #1: 8 quarts of input is showing that I’m extremely overfilled. I filled the trans from the dipstick tube. I waited about 3-4 days and I guess the tube either has ATF still coating the walls, or there really is more than 12+ quarts of fluid in the C6. I’m going to drain the fluid and measure it out to see what’s really in there. And maybe run compressed air down the full tube to push any residual fluid off of the inner wall…
Problem #2: Shifting into drive and accelerating does not get me into third gear. And it struggles to get into 2nd. From a stoplight, I’ll have to rev the motor out in 1st and then take my foot off the “throttle” so that the engine falls down to idle while I’m rolling along at 17+ mph and it falls down into 2nd. It does not do that for third. I can’t get third gear.
am I low on fluid and the tube is giving me a false reading? I know I used 2 full gallons of ATF fluid. Just not trying to add a bunch of fluid and blow the transmission up. I just need to drain to oil and measure how much comes out.
Here’s my configuration. The red box circling the hookup causes the accelerator pedal to bind up and be real stiff
My vacuum pump is pulling suction.
