Default Tech questions, coolant and trans

I have two question, I just changed my motor due to a BHG and now i its running but still need some issues solve.

#1 how do you bleed the coolant system??? this is the way i thought to bleed it but not sure. take the rad cap off and turn the car on and fill it till the bubbles stop!!??

#2 When i shift from park to drive or to reverse it kicks hard as if the trans mount was bad but its brand new. and what does the cable that comes from the trans to the throttle do?? could it need adjustment on the shift linkage??

thanks guys the car feels stronger now just got to work out the bugs

1# Jack the car up so the rad cap is at the highest point. Remove cap and let car sit at about 1500 rpms for about 15 minutes.

2#Hard shifting is a sign of your accumulators sticking in your transmission. Check your fluid level or it may need surgery soon, not sure which. The cable is called a 'kick down' which forces a downshift when you exceed a certain percentage of gas pedal pressure.

Also another note on the coolant issue is to turn the heat on high while still adding fluid and doing the above stated.

Thanks, the trans shifts normal while driving and the fluid is good, but the only time it does the hard shift is while going from park to drive, but i the trans has about 250K maybe time for a new one hope its not i just spent all my money on the motor. thanks again
