I’ve done plenty of transmission work over the years, so the job itself doesn’t worry me especially when it’s not buried in a slammed performance car. I’m seriously considering picking up an AW4. Depending on its condition, I’d either rebuild it properly or do a thorough flush and fit a new TCC...

Yeah big bummer. I’ve done multiple pan drops, getting roughly 4.5 L out each time, and driven it between services over a few days to dilute the old fluid as much as practical without a full cooler flush. It’s now correct ATF+4. Based on the behaviour, I’m leaning strongly toward TCC rather than...

Update: I’ve now received the correct ATF+4 and performed multiple pan drops to flush the system and dilute any remaining mixed fluid. The transmission is running noticeably cooler, which suggests the fluid side is now correct. However, the TCC shudder is still present. At this point, I’m...

Cheers. Once the ATF+4 arrives, I’ll swap it over and report back with the result at the end of the week. 🫡

The only change after the transmission work was the use of a multi-vehicle ATF. Since the 42RLE seems to be a bit particular about fluid friction characteristics, especially with TCC operation, I’m going to swap back to a true ATF+4 as a starting point and see how it behaves. I’m keeping the PCM...

Yes, that aligns with what I suspected. I used a multi-vehicle ATF because it explicitly states compatibility with Chrysler ATF+3 and ATF+4 specifications, so on paper it should have been acceptable. In Australia, genuine ATF+4 isn’t readily available off the shelf and usually has to be...

Hey fellas, I’ve got an issue I’m chasing. I recently had a failed solenoid pack, so I replaced it (new filter and fluid obviously). After reassembly I filled it with fresh fluid — Penrite ATF FS full synthetic multi-vehicle, as it’s listed as suitable for Chrysler ATF+4. Since then I’ve been...
