So I have a 2003 325i. It is 07/2003 meaning that the S5D 250G-TAJT transmission comes from factory on it. I am in the works of a manual swap but now have remembered that the transmission I bought was from a 2005 325i which is the S5D 250G-TBDS. Will the 05 transmission work with my 03 325i...

Any info is greatly appreciated. I have a 2003 330xi with ZF 6 speed. Just did a new clutch kit and flywheel. Got everything together and took her around the block; everything felt amazing! Nothing wrong for the short 10 minute drive. Parked the car, two hours later went for dinner. Put her in...

I just put back in my engine and transmission. The problem is, when I took off the engine I took of the transmission cooler lines and forgot how it was routed so I don't know how to put it back. Can I get some help from someone with experience putting these lines back on or if there's a...

I pulled a 5speed manual transmission out of a parts 2001 330ci to swap into my 2004 330ci this coming summer, but I will not have both the transmission and car in the same vicinity until the summer. To prevent rust or any corrosion, I was wondering if I should let the transmission sit with...

I have recently swapped a different 5HP-19 automatic transmission into my e46 325ci. It was previously the TT version but now has a TU (330i, 530i) version in it. One of the two electrical plugs that go into the transmission does not fit but I cannot find anywhere saying different to all m54...

Hey guys, I’ve been around e46’s for a long time and have always loved them but I’ve owned an e90. I just took a leap and bought a 2004 325CI sulev today for a really great price. The only catch is that it needs a transmission as the previous was taken out by a shop and never put back in. So my...

We took my brothers 2003 BMW 325i automatic to an indie shop a few years back and they alerted us they couldn't communicate with the transmission. Recently, we have been doing a ton of work on the car by ourselves and I have been using the BMW scanner to help get an idea of what is going on with...

Scan with a simple scan tool and get a P0600 code. Take the care home and scan it on INPA & I get code: 217 (CAN bus error -EGS Signal...

Hello fanatics! I need to test my EDS4(torque converter clutch solenoid) and EDS1(main pressure solenoid) solenoids. What is a good way/are the best ways to do so? Is solenoid failure common? I believe my tranny is not keeping pressure, and jerks with the TC clutch under slow acceleration. It...

Hello! This is my first post on the forum, I'm looking to buy my first e46 and i've been test driving a few different models, and while testing one, it had a bad cluster and wouldn't mark the speed i was going, it would stay at 0mph. Everything else was working perfectly. When test driving after...

Just replaced some sensors and the filter inside my transmission. I'm having trouble connecting the male and female plugs outside the transmission. Here's a picture for reference: There must be a special way this plugs in, but I can't seem to get it right. Any idea how to connect them?

I have a 02 325xi and what i thought was the clutch going out or the pivot pin snapped turned out to be that the pivot pin just fell out of its hole. I bought a stainless steel replacement for my upgraded clutch but it fits just like the oem. i can put it all of the way in then pull it out with...

Hey all, Last October I picked up a used 2003 330i to convert into a track build and have been doing most of the standard preventative track maintenance this winter. One of these items is the shift pin/detent replacement since this car had intermittent 5th gear lean. 5th and reverse went by...

Hello everyone, I have had my 2003 325ci for about five years now. Was told my transmission is done and needs to be rebuilt. I have some trouble believing this and I wonder if replacing TCU would work. Please read on... About 2-3 years ago, I started experiencing the transmission limp mode...
