What usually happens with me, is my inability to cope, and intense pain where I want to crawl out of my own skin lets up. ...I don't usually feel major pushing prompts.
I have diagnosed (LOL!) what happens with me is, the baby comes rocketing extremely low during transition, and that's why my transitions are so hellish, AND, why even with a 10 lb 9 oz baby, I push twice and they are out. My homebirth of my biggest baby was when my contractions really turned to painless pressure and I pushed, and learned that's how I work. My transition is pain +pushing prompts, all rolled into one.
With my 7th baby, he was eyebrow presentation, I was at the hospital with my favorite Dr's partner whom I trust fairly well, also. I am a VBA2C x 4 times so I have a great relationship with them..because they trust and support me. Anyway, he was brow and the OB said that he wasn't doing very well and wasn't coming down how mine usually do..I was in horrible pain..got an epidural, it did nothing but crash my blood pressure. He gave me the option of trying like hell to push from 8 to turn him as he descended, or go for a section. I had gone into labor the day I turned 38 weeks, which is WEIRD for me..too early..so I pushed like hell and brought him down from high and 8 cm in about 15 minutes, and he was out. He was very bruised...at first the nurses thought he was blue from hypoxia, then they realized it was bruising!
