5.0 out of 5 stars Saved my old Ford transmission

I put a tube of this in the transmission and noticed within 20 or so miles of driving a massive reduction in the frequency of shudder and veracity of the shuddering. After these results I decided to drop the pan and change the fluid and filter and add another tube of shudder fix I used Mercon LV fluid. Since doing this I've put 20k miles on the SUV and it shifts like new. No shudder ever. My SUV now has about 200k miles on it. I recommend first using this as a diagnostic tool, it you see improvement then change the fluid and filter and a tube of shudder fix.

5.0 out of 5 stars 2006 Buick with 4t65e Transmission

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!

Hard shifts on a 2001 Chevy 2500hd. Don’t really believe in magic. This is magic in a bottle. Instantly fixed hard shifts. Had the trans fluid changed new filter, hard shifts came back. Put the magic juice back in problem solved a second time. WOW!

5.0 out of 5 stars Works great!

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.

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

5.0 out of 5 stars 2016 GMC with Allison 6 speed shudder in tow haul

A. · May 4, 2025

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!!!

5.0 out of 5 stars It worked!!

I don’t know what this has in it but it works. I was skeptical at first but it has made a noticeable difference in how my car shifts.

Lo utilicé en la caja automática que a veces hacia algun tiron leve y suaviza mucho el andar. Lo que hace básicamente es rejuvenecer las juntas de goma que van en la caja.

MAGICAL 2oz bottle.

Just got this product. Easily the best thing I have EVER bought on Bolo. Magical.Have a 2015 Camry 2.5L with an annoying shudder. For the life of me I didn't know what it was and then people told me its a Torque converter issue. It's common in this model and others.Anyway long story short, my mechanic told me to do a drain and fill and put this magical lube into one of the ATF fluids. He pumped out the old fluid and put in the new fluid which was mixed with 2oz of shudder fixx.VOILA! The shudder is completely gone. The shifting is like butter. I'm in love.Thank YOU! Lovely, lovely product.

Works better than expected
