I bought a 2019 Tacoma TRD off road with 65,000 miles and a manual transmission. They just put in a new clutch, master cylinder and slave cylinder with all new fluid. It absolutely is much better.
When it’s cold out like today 20 degrees, this the hydraulic fluid is real thick naturally. However, it shifts and drives much better than when it’s fully warmed up and the fluid is heated up and thinner. I’m having something going on when up shifting to 5th and 6th gear. When letting off the clutch in those specific gears, there is a slight thump or little jerk I would say. It’s intermittent in both these gears and only these gears. When the fluid is cold and thick like this morning, it don’t do it. I drove about 15 miles and shifted in and out of these gears a few times this morning no problem. Then after dropping kid off, as soon as I jump on highway and get up to speed and shift into 5th then sixth it does it. Please keep in mind I learned how to drive on a manual. Several of my first cars and my work trucks have and are manual transmission. I know how to drive one. Does anyone have any experience or knowledge about this? Thanks you.

What you’re experiencing is likely normal for your truck. Cold hydraulic fluid is thicker and can mask small jerks, but once it warms up and thins, you might feel a slight thump in 5th and 6th gears due to driveline lash or how the synchronizers engage under load. Since your clutch, master, and slave are new and it shifts fine otherwise, this is probably just the normal behavior of the transmission and drivetrain. As long as there’s no grinding, slipping, or difficulty shifting, it’s not a serious issue. Slight adjustments in clutch release timing in higher gears can help smooth it out.Originally Posted by Steve007

This sounds less like a hydraulic issue and more like driveline behavior. Since it only happens in 5th and 6th when warm, it’s likely related to driveline slack or how the new clutch engages under low torque multiplication. Cold, thicker fluid can mask this, which is why it feels smoother at low temps. Possible causes include slight driveline play, mounts allowing movement, or normal characteristics of a new clutch once warmed up. If there’s no slipping, grinding, or worsening, it’s usually not a major issue, but checking mounts and fluid specs is a good idea.Originally Posted by Steve007

Why is there a girl dad tshirt link in your quoted post from the OP? Are you a real person or a bot?
