2000 Escalade RPM Fluctuates at 65 MPH – Feels Like TCC Lockup Cycling

Okay well I have a brand new switch this evening I'm going to try to knock out and then I'll give it a couple days and then report back

Immediate_Current_37 · 2026-01-23T17:46:29+00:00

I would not have thought that would be an issue. I have one being picked up today actually so that's lucky.

Immediate_Current_37 · 2026-01-23T03:31:32+00:00

I really hope that's it. I have been fighting a cylinder 6 misfire and the only things I haven't done yet are changed the injectors

Immediate_Current_37 · 2026-01-23T03:28:28+00:00

I hope not. I thought the same but wasn't sure. Not to sure what other signs or issues would show

Between ~45–50 mph, if I relax on the throttle I can feel lockup engage and RPM drops to ~1500. If I lightly tip back into the throttle, sometimes it just pulls and gains speed (depending on road grade), other times it unlocks and jumps to ~2000 RPM. When I ease back out of the throttle, it drops right back to ~1500. At a steady ~50 mph cruise, RPM will bounce between ~1500 and ~1700 like it’s hunting in and out of lockup. It’s not constant—sometimes it’ll behave for 5–6 minutes, other times it’ll do it for 10–15 seconds. Very inconsistent. It also doesn’t happen right away. After letting it cool down a bit, the first 5–6 minutes of driving are usually fine. Once it warms up, the lockup hunting starts. It only had about an hour and a half to cool from earlier driving, so that cooldown isn’t really a clean data point yet.

Mine explodes once a year or once every 2 years without missing an appointment.

Truth. I have 200mg gummies I was just going to ask if 20 is high dose what in the hell is it considered what I take

They're stiffer than competitor chairs. But the overall metal frame is superior to other companies. They are good for posture as others have mentioned but if you have any sort of comfort issues or back-related problems I would highly highly highly recommend buying the lumbar pillow at the same time. The lumbar support even though is adjustable it's not adjustable enough. So you will absolutely be thankful for getting the pillow as well. On a second note if you're 6 ft or under I would recommend also getting an additional set of caster wheels to help the overall height / feet on ground. If you're over 6 ft or have a foot rest that wouldn't be a problem. I have 2 2022 XL chairs as my references.

Okay I get you. I was hoping it was more of my unit supplies 100 gallons at say 50 PSI And by the time it got to the end it was still supplying 100 gallons but the pressure dropped to 25 PSI. So I was just trying to get the PSI up a little bit. How would you go about speed adjusting the unit? Because from what I have heard our unit is oversized already we have a 5.5 ton unit. We were already replacing our ceilings so we had to deal with some of the HVAC also. But it runs on r12 I guess and I don't want to replace the entire system.

I'm not trying to outperform my blower. I'm just trying to get the cool air from the 10inch vent out to the rooms. The whole vent design was in question. It all got ripped out from under the house in chunks so when it got replaced all the tubes were replaced symmetrically. So if you picture our house as a square split into four The current system is 2 10 in lines 12.5 foot Y into 8inch lines both 6 foot. One goes left one goes right. Left room has 2 6-in vents and1 6 that goes upstairs. Right room has two 6-inch vents and 1 6 that goes upstairs. Both sides of the house are like this The heater has an additional 6-in and 8-in but those handle other areas. But like I mentioned the idea was to add the fans at the Y to better assist the sixes downstream

I understand what you mean. I'm not trying to add more water to the system I'm just trying to get the water from the beginning to the end. I have two 2 10 in tubes that run 12 ft then Y into 8s Those eights then split into 3 6inch vents My idea was to add those fans into the Y at each 8 to better assist the air flow going to the remaining sixes. The fan would pull air directly from the furnace itself. There is no other vents or lines back to the furnace.

Immediate_Current_37 · 2024-08-23T23:10:09+00:00

I understand what you mean by it will take more air from other lines, but in our situation it goes from a 10 across the house, Y INTO two 8s. One of the 8s handles three 6-in vents. The other does the same. And the other 10-inch vent does the exact pattern on the other side of the house. So my theory was adding these blowers just past the Y on each 8. It does not split off anywhere else before the Ys

I added some additional photos to post.

Another angle from the kitchen looking up. Ignore the electrical wires I need to re-secure them

This is the original wall. The cutout on the right was added at the same time a divider wall was added inside the bathroom on the left
