Belt slip noise in manual mode shifting >5.5k rpm?
#121
Just got my
Monster back from massive 60k service . The tech told me it's he belt, pulley , or AC. I told him my AC cycles every 10 seconds causing a slight rpm fluctuation and my tensioner and pulley have already been replaced. I want them to replace my AC compressor . Going to talk to the foreman and Lexus extra care adjuster . It's bs that o have a warranty and they don't want to attempt a fix. I don't want the car screatching when I shift

I have a "slip" noise in a 2012 isf with 25k miles. I believe it to be the clutch packs in the trans. With a locked torque converter, something has to slip. It seems to sound like it comes from below the car in my ears. Heard the same sound in other isf cars. I don't blame drive belts for it.

I just had my second round of drivebelt and pulley don't this afternoon. It got rid of it. I'm going to wait for it to come back and then the warranty people will replace the AC. I also have a rpm variance at idle every 5 seconds with AC on. Formeman said it's the AC Or belt. I replaced the belt and pulley and they will replace the AC if noise comes back. It's not tranny

I was getting this noise was well. I replaced my belt with the Gates Racing Belt from rockauto.com and it seems to be holding up really well. It's been two months and no noise.

Didn't have as much luck as some of you here. I'm having the issue on my 2012 with only 11k miles. Had the tech confirm the slipping noise on a test drive. However they were saying that it wouldn't be fixed under the powertrain warrranty.
Im going to look to replace the belt out of pocket. Should I go OEM or aftermarket?? I heard someone mention the rock auto racing belt? I'm also considering gates green and the continental belt. Any suggestions here?

Revival. My car does this and was heard easily through a camera recording from the front.
Accessory belt confirmation? Got a can of belt conditioner lying around. Couldn't hurt to spray it

Serp belt slip
I had this noise during hard accel and manual shifting near redline. Stock 2012 IS-F, MPSS tires. I thought it was transmission clutches. Installed new serpentine belt and the noise went away. Old belt is in the trunk as a spare.

The old belts are trash after a few years or 60k miles.
I'm on my 3rd or 4th belt already since 2009.
