Your whole drivetrain might be shifting under stress.
Engine mounts, transmission mounts and diff bushings may need to be checked and changed if worn out.

Redline D4ATF much better than OEM

I was thinking about using the redline atf and I'm thinking about trying it. I've heard it gives buttery smooth shifting

If you drive it during winter how cold does it get?

OP, hopefully your problem is something simpler (fluid, CDV), but another thing to consider for jerkiness when shifting, especially in lower gears, is a failing dual mass flywheel. When mine started going bad I had to baby it in the lower gears. It made it really hard to shift smoothly.

In RealOEM it appears the 320i has the same transmission, clutch and flywheel setup as 325i. If that's the case, you could ditch a bum DMF and install a SMF conversion kit like I did on my car.

Speaking of SMF conversion from Valeo.

Anyone know what is actually different between 01-02 325 clutch and 03-05 325 clutch?
Part numbers different for both SMF and DMF setups.

In winter it gets like 46 degrees at the absolute worst. I have never seen snow fall within a 100 mile radius of my home. So I think D4 would be okay right?

I don't have experience with changing it on an E46, but I do have a positive experience with the change on another car.

A common upgrade for the original Sentra SE-R was a short shifter, however, it made the shifts rather notchy. The switch to Redline gear oil almost universally improved the shift quality. I certainly noticed it. While most gear oil producers have a package of additives, it seems the Redline gear oil has some additives that help the synchros mesh more smoothly. Motul makes an excellent gear oil for manual gearboxes, but I'd rather roll around in cat poop than get a drop of that stuff on me. That is the most foul smelling stuff. I used it once and vowed NEVER again.

46F is roughly 7C so warm winter?? I thought all Canada was colder than that in winter unless of course you meant -46F?

Then Redline MTL is the correct fluid

Just FYI - I run Pentosin MTF2 in the 328Ci and 98 Z3, 2.8. No issues thus far.

Pm me. I live in Southern California, Redlands to be exact. And the amsoil synchromesh was the best thing in my manual trans. It's a thicker fluid than the atf but it doesn't get cold enough here to need the thin atf style fluids

Hopefully your tranny doesn't end up like mine. First was the clucking, then rough shifts, followed by some vibrations, and now a trip to the dealer and 2000 later I find out the deep groove ball bearings went out and took the clutch and flywheel with it. However without the cdv I could have detected clutch wear sooner so I will definitely be performing a fluid flush for my diff, tranny, and master and slave cylinder along with the a cdv delete. All of this from a 2 owner car (I'm the second) first was a 63 year old germany woman.

Rofl that's how I feel when I've changed the dif fluid on my cars.
