I finally got everything put back together the new radiator is working great the flush and new coolant refill is great. However, I am confused on the ATF flush process or if I am doing something wrong. I filled the transmission up with about 7.5L of Shell 134 and tried the flush out of the return line on top of the radiator. When I turned the car on and left it in park it started to come out into the bucket, but was looking like it had too much air pockets (1st video) also it was slow flowing, I've seen others do it and it was a quick flow to fill the bucket, am I doing this correctly? Whatever drained out I refilled also.
The other thing is the dipstick was measuring as if nothing was showing up between the cold/hot marks, I can confirm that there is no leaking anywhere so what is happening to the fluid. BTW, the dip stick does not go in all the way about 10" is still out I wonder if this is by design?
I didn't take the car out on the road yet since I didn't want to get stuck but, was able to move through all the gears on the gear shifter N>D was hard at first, I am able to move the car so the transmission is engaging but sounds bad from Reverse to Drive and vice versa almost like rusty hinges on a door (2nd video) the car was warmed up for almost 15 minutes at the time of the video.
My plan for now is to leave the car overnight and measure again in the AM and actually try the flush again from the cooler line and see if it improves, and then drain the torque converter and pan again and refill with Fuchs ATF.
The good part is that the spinning noise at startup probably from the torque converter, the jumpy RPM reading, and hard thump noise getting into gear issues are gone.
BTW, what is the actual capacity for ATF on this transmission, I am seeing between 7.5 - 9 liters in my research what is the correct amount?
