Lubegard19610 Instant Shudder Fix

Bought this for my 102,000 mile 2006 Buick Lucerne. Bought it at 98,000 miles and since day 1 its had a horrible lockup shudder, has gotten slightly better over time, but still there. Started seeing this stuff pop up and figured what do I have to lose other than 17$ being I ordered 2 tubes. Put it in this morning and went for a drive. Got to lock up and the shudder….ITS GONE! It works! Anyone with a GM 4t65e Transmission, try this stuff!

I don’t know what’s in this little 2oz tube that makes the transmission shift smoother, but it really seems to work well. I have a 2013 Chrysler Town and Country minivan. The transmission had 140k miles on it and a was way overdue for a fluid and filter change. It was shifting harshly. I did the fluid and filter change and it helped a lot. I read about this stuff on a forum so I figured I give it a try. I added it about 200 miles after the filter change. It really softened the shifts to be buttery smooth. I don’t really understand how it works but it’s going in all my cars when I do trans fluids changes from now on.

Based on web warriors reviews I figured it would be worth a shot. My truck was shuddering in tow haul mode 4th and 5th while accelerating. You'd swear it was an engine random misfire. In Mopar world they'd call it "fish bite". Pretty sure it was torq converter shudder. Wouldn't do it in regular (non tow) mode or any other gears. Well I'll be dipped, this stuff after 20miles has the condition gone. Liquid magic. Overly sensitive wife says all shifts are better. I'm religious on trans fluid servicing but I'm going to guess the Castrol fluid spec'd isn't enough... Very pleased. Would recommend trying if you suspect converter lockup shudder in your going to town rig.

I drive a 2015 Escalade with only 65K miles and started getting the dreaded transmission shudder that GM vehicles are notorious for. I previously had my transmission fluid changed at 40K miles for a hard shift, so was skeptical when the shudder started creeping up (sounds like driving over rumble strips on the highway). I was already considering options for bringing it into the dealer and at worst case, trading it in.Came across a thread that recommended this and decided to give it a try after reading the reviews. Low and behold, the transmission shudder is COMPLETELY GONE!! I noticed before, shuddering was most prevalent around 30 mph or when I had cruise control on. I was able to watch the transmission temperature fluid temperature and it would start acting up at about 130° or higher. Started working on the first drive and the transmission temperatures run noticeably cooler as well, operating at about 140° to 150°, whereas, it used to operate nominally at 175°.HIGHLY RECOMMEND AND TRY BEFORE YOU TAKE IT INTO THE SHOP!!!

This product is amazing and does exactly as it says. It was a lifesaver.

Worked right away, I think my transmission is too far from saving but I noticed a difference right away after adding this in the fluid. The best part is that It isn't very much so you won't overflow your transmission fluid simply adding it in. Other items require a bit of removal because of the volume, but not this.

I have had a shutter in my 2015 f150 eco boost for years! I flushed transmission fluid and added 2 oz of this and boom no shutter within miles. Product is insane no brainer if you are experiencing that issue for the price.

I was skeptical but it did make my transmission shifts smoother and more responsive. Didn’t fix the shudder since the issue was with a single defective spark plug coil pack. This product enhanced my transmission performance however.
