Help Trans Problem

[69Explorer69]

ok here it goes my front seal went out 2 weeks ago and i went to replace it got everything put back together.the trans and all went in with no problems at all.Well when i drive down the road i can feel it shift into 1st 2nd but when it gets to third it seems like it doesnt want to shift.What can it be? I wanna rule out the Tq because 1st and 2nd shifts smoothly with no problems at all..I know i lost alot of fluid and i only stuck 5 quarts back in.

Could it be because there is not enough fluid in the TQ to shift it in to the nexted gear.If it helps when i am at 75 mph i am close to 3000rpms.Please help as this is our only car and i am still driveing it to get my wife to work i just gotta stay under 55mph so the rpms wont go so high.What can i do to fix it i am really in need of help.Thanks all

Make sure that you plugged the vacuum line into the modulator. You might want to adjust the kickdown cable too.
