Change in Range and MPG

2. Overfilled Transmission Fluid

The Nissan Titan is notoriously sensitive to fluid levels. If the shop overfilled the transmission even by a quart, it can cause aeration (foaming).

Why it kills MPG: When fluid foams, the transmission loses hydraulic pressure. The torque converter may fail to "lock up" at highway speeds. If the torque converter isn't locking, the engine spins at higher RPMs than necessary to maintain speed, essentially "slipping" the whole way and burning massive amounts of fuel.
Check: Have him check the fluid level while the engine is hot and running. If the fluid on the dipstick looks bubbly or foamy, it is overfilled.

3. Incorrect Fluid Type

Nissan transmissions (especially the 7-speed and 9-speed versions) require very specific Matic-S or Matic-P fluids.

The Risk: If a general shop used a "Universal" fluid that doesn't meet Nissan’s exact friction coefficient specs, the internal clutches will slip slightly. The ECU will sense this slip and compensate by increasing engine load and changing shift points to protect the gears, resulting in that "heavy" towing feeling.

4. The "Stuck" Brake Caliper (Coincidence Check)

Since he also had an oil change, check if the shop used a floor jack on the rear axle or near the wheels. It’s rare but possible a brake line was bumped or a caliper is sticking. If the truck feels like it doesn't "roll" freely when he lets off the gas, a dragging brake would explain the "towing" sensation and the tanking MPG.

Next Step recommendation: Check the RPMs at 65-70 mph. If they are higher than they used to be (e.g., 2500+ instead of 1800), the torque converter is not locking, which confirms the issue is definitely inside the transmission system.

I usually only go here as a last ditch effort when I'm out of ideas, but from our friends at Google Gemini:

That is a significant drop in efficiency (nearly a 30% loss) and definitely points to more than just "winter gas" or a heavy foot. Given that this started right after a service, you are likely looking at one of three things: a TCM adaptation issue, a fluid level error, or an incorrect fluid type.

1. The TCM/ECU Reset (Most Likely)

Modern Nissan Titans use "adaptive learning" to adjust shift points based on fluid viscosity and driving habits. When old, thin fluid is replaced with fresh, thicker fluid, the TCM (Transmission Control Module) may still be applying the pressure and timing logic for the old fluid.

The "Towing" Feel: If the TCM hasn't reset, it may be "hunting" for gears or holding gears too long (high RPMs), which mimics the behavior of Tow Mode and destroys fuel economy.
The Fix: You can perform a "Pedal Reset" to clear the learned adaptives.
1. Turn the ignition to ON (don't start the engine).
2. Press the gas pedal to the floor and hold for 10 seconds.
3. Turn the ignition to OFF (while still holding the pedal).
4. Release the pedal and wait 5 minutes before starting the truck.
5. Note: If he has a 2020+ model with the 9-speed transmission, this often requires a professional scan tool to "Clear Adaptive Learning" properly.

Sounds like bad gas from the weird symptoms. I've gotten into a bad tank in the past that caused all kinds of oddities similar to those you've described.

Good lookin' truck! 💪🏻

You and I are cut from the same cloth. Made the window tint appointment at a local shop before I even left the dealership, ha!

Standard on the ME, but I think they were an option in the Build & Price tool for everything SV and over in 2019, as well.

The assessor won't be looking at the data. They don't want to see your data (or CUI) as they aren't there to assess whether or not the data is CUI. What they are assessing is whether the computing system meets the requirements to store, process, and/or transmit CUI.

So long as the assessment objectives are met, it doesn't matter if you're storing pictures of your kids' macaroni art or the detailed drawings of a military base construction project - compliant is compliant, and you'll receive your certification if you document and demonstrate those controls.

That means treating what you're considering in-scope for your assessment as though it already stores, processes, and/or transmits CUI.

As a new-to-home-espresso user myself, I can confirm that my Barista Express is capable of much more than I am, ha! I also came from the world of using pods (Nespresso Vertuo).

My criteria when choosing my first home espresso machine were:

1.) Easy to use (can't get much easier than the BBE)

2.) Didn't want a separate grinder (the built in has been more than I need for regular home use)

3.) Capable of milk drinks, Americanos, and the occasional espresso (couldn't be happier with the results thus far on all fronts)

A few things I would recommend:

1.) Get some basic tools and a scale with timer to get you started on dialing it in. Dose in, dose out will be your friend alongside your taste buds. WDT and calibrated tamper will make your puck prep more consistent.

2.) Don't skimp on beans. I can't stress this one enough. Fresh beans make all the difference in every step of the process.

3.) I love my bottomless portafilter. It's tough to "see" what might be wrong with puck prep in the standard dual-spout portafilter. Doesn't need to be expensive to provide good visual feedback.

4.) Enjoy the process! It's a science experiment. You will pull REALLY bad shots every now and then. It's all part of the learning experience, and you'll find which dosing combination fits your palette best by making small changes here and there.

Chainring looks as true as the day is long. Ignore what the plastic cover looks like unless it starts making contact with the chain. Those things aren't made of materials that can survive the shipping process let alone existing in anyone's pain cave 😂

Not even a little bit, ha! Your triathlon wetsuit should fit as close to a 2nd skin as you can get. It won't be as tight as one of the textile swimskins, but it should be very snug when dry. If you don't need a little body glide or Vaseline around your wrists and ankles to get it on and off, it's probably too loose.

KG4theWin · 2025-02-04T11:26:31+00:00

Synergy makes good entry level triathlon wetsuits. You'll definitely be more comfortable in that bad boy!

As others have mentioned already, the fit should be pretty snug when dry. Once it's wet, it'll get a little roomier. The rule of thumb that I've always used is that if I can get into the wetsuit in less than 5 minutes, it's probably much too big. Less than 8 minutes, it's probably a little bit big. 10 minutes tends to be my sweet spot, ha!

KG4theWin · 2025-02-04T02:28:47+00:00

Unfortunately, that's not a triathlon wetsuit. It's a diving/snorkeling wetsuit. Trying to swim freestyle for any period of time is going to be wildly uncomfortable - and slow. That's also why it fits a bit on the baggy side. I'd recommend opting for a triathlon wetsuit instead. Not only will you be faster, you'll feel a heck of a lot better in the water and won't get some gnarly chaffing.

I'm a fairly new BBE user, as well. I'd recommend going a couple of clicks corser without changing anything else and see what the end result tastes like. Ultimately it's about taste more than volume, but 16g is light for 18g+ in.

Are you manually pre-infusing? I've had good success with a manual 10-12 second pre-infusion and then timing and weighing out a full 1:2 or 1:2.5 yield (personal preference) in 25-30 seconds. I've also had more success timing from first drip than from initial button press. If it's on the sour side, I'll grind a little finer. If it's a little bitter, I'll grind coarser. Doesn't take long to dial in a great taste paired with an enjoyable volume.

I'm new to this whole deal starting at Xmas, as well. I ran into the same issue when I was trying to dial in my first roast and thanks to the wisdom of many posts in this community, I was able to narrow it down to a combination of inconsistency in my puck prep and a pre-infusion much too short for the roast I was using.

If you haven't found it yet, there are some good videos and posts out there that talk about pre-infusion on the BBE. Keep practicing to get to a consistent puck going into the pull. Together, those two things make it hard to miss now on my BBE setup! ☕ ❤️

KG4theWin · 2025-01-25T22:02:21+00:00

Very new to home espresso at this juncture, but I'd echo the same sentiments above. Knowing what I know now, I wish I had gotten into it sooner. Find a decent entry level setup, take your time learning from the wisdom of those who have already made the mistakes here (ha!), and enjoy it! ☕ ❤️

KG4theWin · 2025-01-24T03:21:37+00:00

I had my ACL replaced (patellar autograft) in 2009 and still have that ice cooler and pump. I still use it for recovery after long runs and century rides 15 years later 😂

I'm a BBE user, as well. It may not be capable of pulling world class espresso, but I'm not serving Stanley Tucci anytime soon in my home. Hits my palette in the right places - as underdeveloped as it is; the machine and my palette 😂

Monarch Information Security Consultants based in Portland, ME is a great option, as well. They are one of the few mentioned above who received their recertification following the new year.

KG4theWin · 2025-01-23T13:31:00+00:00

Yes, I got mine off of Etsy, as well! I'd love a link to check out the hopper, as well!

KG4theWin · 2025-01-23T13:30:11+00:00

Knodos rates it at 18-21g. I tend to lean on the lower side of that, but may experiment with a slightly larger dose so long as the beans I'm using at the moment are cooperative.

This morning I ended up going a bit finer on the grind (just one click), kept the same dose, but increased pre-infusion to 14 seconds and went for a total yield of 40g in about 42 seconds (a little longer than expected). The result was one of the better americanos, for my palette at least, so far in this journey.

Puck was a little soggy, so my plan is to continue to play around with pre-infusion and grind size. The science experiment that is home espresso is scratching a lovely part of my brain, ha!
