At what speed?
Ideally, especially on steep inclines, you’re better off staying in 2nd gear (or even 1st gear, if you’re fully loaded).
Depending on how steep the hill is and your speed you may be lugging the engine in 3rd gear. Of course that puts the engine under more strain so if there is any weakness in the ignition, fuel system, emissions system, or engine of that 38-year-old car it's going to show up under those conditions.
Also I forgot to mention it makes like some noises in the rear of the car like a thumping noise
That could be worn suspension bushings, CV joints, or shocks in the independent rear suspension.
Okay great cause I thought it was the driveshaft or something like that and thanks for the info bro.
Well driveshaft joints are also a possibility of course but with independent rear suspension the differential is fixed in place and the driveshaft doesn't move around like the CV joints on the halfshafts do. Given the age of the car it's worth checking them. (BMWs of that era are very well made but age takes its toll.)
