Does Lucas Transmission Fix really work? - And will it stop slipping, and miss-shifting?

This is a follow up video to the video I made testing the Lucas Stop-Leak product on my 2007 Subaru Impreza. I was so happy with how well that product worked, I had to try the transmission product too.

I took out 24 fl oz’s of trans fluid and put the full bottle in (24floz’s) in my 98 ford expidition and within one mile the transmission was shifting fine when i gunned it. Before it would stall and not shift at all unless i let go of the gas. This product really works

When I use Lucas oil products I usually fill my sink with hot water and let the bottle set in it awhile before using it. Worst transmission I used it in wouldn't do anything past 1st gear it would slip like crazy after the Lucas it shifted fine I got 6 months out of it until it finally went out all together.

Good proof cencerning the Lucas transmission additive product. Thanks

I use it as preventative maintenance in my 07-09 GM 6L80E Transmissions. I put it directly in the pan prior to bolting up pan during fluid-filter services every 50K miles and they are still working perfectly after 250K+ miles.

Youre right, It's pretty good stuff, a couple years ago I was driving my 05 ford f150 in Colorado it started shifting kind of wonky and, I stopped and checked it to find the level had gotten very low on the stick, I found an O'Reilly's and filled it up with regular atf and used the lucas for the last bottle, it seemed to like it, and it hasn't had that problem since thousands of miles later. It's not magic but I'd say it's well worth the 15 20 bucks if you have a transmission that may have overheated or ran low on fluid or a use for heavy duty vehicles that are run hard.

I have an 09 Forester with the 4EAT. 1-2 and 3-4 exhibit the same symptoms you're seeing between 3-4 but only when it's cold out. 230, 000km I expect no less however I'm glad this worked! I will be giving it a shot before I schedule a rebuild. Thank you for your service!

I'm having this problem with my 1996 Honda Accord V6 it has a rebuilt transmission in it. I've driven less than 5 me I'm still having problems so I really appreciate the video it's super helpful I'm going to drive it and just do the shift manually so that I can bypass the torque converter so it's not having the problem that it does indeed for the RPM keeps going higher for my car it doesn't go back and forth. The transmission has been replaced with a rebuilt with low mileage 3 years ago. The problem with it right now is that it was low on transmission fluid and I put a half a quart of the wrong stuff in this Honda it requires particular especially for honda. I thought I could come home and drain it out but it really started screwing up so that didn't help at all! Always check your transmission fluid before you put it in! * 3 I really hope this helps any other Honda person's car. Again very helpful super appreciate this

It’s been a year since you posted this video- I have an 08’ 2.4 Accord with almost 220, 000 miles. My transmission does the exact same thing when it’s not warmed up- from 2nd to 3rd there’s a mule kick of a shift. Once I’ve driven for at least 20-30 minutes it goes the whole day with no issues. It’s not the weather as I live in Malaysia where it’s always hot. Will definitely try this. Thankfully we have a local supplier. Cheers!

Well, I tried this yesterday and I got a 07 Maxima with a slippin' transmission and it did the hardest slips once I hit exactly 115K miles, which shouldn't be much. So I tried this yesterday. I heated up the bottle with hot water, like youtubers mentioned. I test drove my car. The rpm's were a hint sluggish but not much. It did change gears and I did hit the gas hard once to go from 3K to 6K RRMs within minimal seconds. I did notice a difference in my car, about 65%. NOW, today being Day 2....I'm going to drive it more. I am nervous but I will say this - I enjoyed my drive yesterday....I even got confident enough to upset people at the red light with my car's Subs :)

I'm going to do this to my 2004 subaru forester. It has a super funky transmission. I also had a 2002 subaru legacy before this one & it shifted the same so I think it's very common for these subarus from 2000 to 2004.

I get intermittent slip, usually during lockup, on the highway. P0741 code comes up. I'm going to try this. My transmission has 340xxxkm on it

There are so many different opinions about this additive. Some people say it works well. Others say it leads to more problems down the road. One of these cons is the formula that is designed to recondition old dry seals. Basically, it causes them to swell up which helps them do their job better in their worn condition however this swelling can cause seal failure resulting in pesky leaks. Once this stuff has ran through the entire transmission coating everything the only solution to fix the unintended damage is to get a full overhaul.

On the other hand, how well this stuff works or doesn't is definitely dependent on the condition of the transmission's internal parts. If your plan is to eventually get a rebuild down the road but you want some relief from the annoying hiccups in the short term this stuff is worth a try. Just don't expect instant results. Give it at least 150 to 200 miles to do what it can.

I had a 76 F-150 pickup back in 87k it to AAmco Transmission, they told me I needed a new one, instead I pumped it full of Sealer & conditioner until the leak stoped. The tranny out lasted three engines.

[tommyho]

I used it on my 4th gen 4Runner it didn’t work and I think it made it worst when I gun the gas peddle it slip or lag 2nd time. Usually only slip on 1st gear

[officialWWM]

I put this stuff in my old Jeep and the trans shifts just like a new one!

[marcelfilms]

I add a little ATF to my manual gearbox and it improves shifting a lot

[samyeomans]

On my car, the same issue with the torque converter rpm bounce thing. I’m gonna give this a go. Good to know not to expect instant results.

[zakburnett]

Sounds like you might have benefited more from the trans cleaner part of it, seafoam makes one you gotta change the fluid after tho don't do it to high mileage cars or cars with really burnt fluid/extreme slippage it'll just wash the clutch plates away

[BLRBOM]

Very good product.. stopped my trans- slipping, , go a complete flush change...

[LifeMonger]

Have a 2010 Subaru forester having same issue, gonna try this.
