To everyone who is looking to change their own fluid, I searched through a couple of terms and could not find what I was looking for on our forum, so I will post it here: 6SP Manual - 2.0 qts MOPAR P/N - 68092630AA RedLine - 50604 The MOPAR fluid is usually $30+ and probably up to $40 depending on your local dealership. However, RedLine has apparently come out with an exact spec fluid for our 6 speeds at less than $20 a qt. I will be putting in 2qts of RedLine as soon as it comes in and I'll report back with any feedback on it, though for it being an exact match, it shouldn't change anything. RedLine also has an 80 and 85 weight that is reported to work for the Darts and Romeos using our trans, but personally, I would much rather have an exact match fluid and I'm glad RedLine agrees. Lastly, there is a Castrol Synchromesh that is reported to have been used by others and works, but, again, RedLine makes an exact and I feel like that is your best bet. Full disclosure: I do not work for RedLine, nor do I receive any monetary benefit from them. This is my personal research. Use at your own risk
Thanks for posting. Good information. RedLine is probably a better lubricant anyways. Might as well go for the better product and save some money in the process.
So I'm finally getting around to changing this, but I have not found a single tutorial on YouTube, or online, so here's to hoping I don't break something.
Update: transmission fluid change all done. Once I had all the required tools, it was easy. While I didn't find any tutorials on Jeep Renegade 1.4L trans fluid changes specifically, I remembered once I had the Jeep in the air, that we share the same engine/transmission with other FCA cars. There are quite a few tutorials on Dodge Darts. So, here's a good video I used this morning: A few notes: 1. You will need a 12mm inverted hex drive/alan wrench to remove the drain port. Home depot has 1/2 drive impact ones. There was just enough room between the subframe and transmission to fit it with a breaker/ratchet. If you can find a 3/8 drive, it will make your life easier. Mine was pretty stuck in there after 75k miles (I don't believe the dealer even monkeyed with it), so regardless of what size you get you'll *probably* need a breaker bar. YMMV. 2. Make sure your Jeep is level. I pulled the fill plug and got soaked. Now, it wasn't angled back that far, but I suppose it could've been angled far enough. I think that it's possible it was overfilled. I also had a good amount of metal shavings in mine, so if you're running a manual, be vigilant in your transmission fluid changes. I don't offroad mine and it doesn't tow, but I definitely needed a fluid change, so the manual stating that it only needs changing after 50k mi with those caveats, seems incorrect. 3. Have some sort of deflector for the fluid stream as it comes out of the drain plug as it will hit the subframe otherwise. There's just not a lot of room. 4. You're going to need some sort of transfer method to fill with the new fluid, even if you take off the wheel. I used a 3ft ish section of 5/8 in OD tubing from Home Depot with one of their funnels wedged into it and it worked great with the wheel on. If you already have an extended funnel, you can probably use it if you take the wheel off, but tubing's cheap, so why not? 5. Would recommend measuring out your 80% of a quart. Easy peasy, no other measuring needed. After checking research, it seems it takes a full 2qts of fluid. I'll be putting in the last small bit of fluid tomorrow. (This was the post I used when assuming I was to use 1.8 qts of fluid: https://www.dodge-dart.org/threads/manual-transmission-fluid-change.62962/ If you read towards the top of the post, this is for a 2.0L Dart engine, which is not the same as a 1.4L Renegade. Use 2.0 qts of fluid.) The Redline fluid feels great after what was in there. Time will tell how it holds up, but shifts are much softer and seem to click in much better.
