My Ride: 1999 328i
Exclamation Shaking, popping, rattling and no acceleration!

Hi guys, first post, so clearly I'm new at this. I have a 1999 328i, automatic with the shitty ZF tranny (which failed and I've replaced) the car has 153k on it and the tranny 90k.
Ive been having a strange issue lately, not sure if it has anything to do with the transmission or not. When I accelerate (which is poor to begin with) and I make it into 5th gear range (specifically 100-125km/h), the car shakes, makes a thudding noise which I can feel shake the whole car (kind of like a dull thump), and the RPM's jump between 2400-3000 sporadically without accelerating the car.
The only way to get passed it is to floor it so the car downshifts into 4th-so I can accelerate into the 130km/h range where I can just cruise at the speed until I have to repeat this.
Please help, because I have no idea what this is
Also, no check engine light.

Ps. Sorry if there is a post about this already, but having trouble finding one.

Also not sure if this is relevant, but when I'm at a light the rpm's don't hold steady. One time they dropped low enough to stall the car. (Probably making me the one of very few people to stall an automatic at a light)
