has anyone ever tried Lucas trans fix on their Q

[JOHNQ]

can lucas trans fix harm the trans in anyway?

[galvy22]

i used lucas on all my cars when i 1st get them never had a problem

[JOHNQ]

have you ever put it in the trans?

[elwesso]

I dont like additives except things made by lubeguard and BG. Why do you want to add LUCAS to your trans?

[gammer_ghn]

I have it helps with the kicks and nicks a little. Do it but don't put too much so you don't over fill the transmission.

yeah it helped with kicks in my other car i just put it in all my cars to help prevent that kind of stuff

[JOHNQ]

i want to put it in cause my 2000AE shifts are rough. it does not slip at all just when it shifts from second there is a flat spot pause then when it connects it is not very smooth much like what paranoidjack describes he has experienced with his 2000AE when he first got it. i did put that redlubegard when i did a drain and fill with mobil 1 atf but it did not improve

[Kiven422]

I've heard a couple of good experiences. When I took a look at the fluid after a couple of days driving with that stuff... it seemed like it really thinned out the fluid.

My experience with it was nothing good but I used it on a transmission that was already going bad.

[Jesda]

Had a friend whose 85 Maxima ran low on ATF and stopped shifting. Added a bottle of Lucas and was able to drive it for a few months until it finally kicked the bucket.

I say, keep a bottle in the trunk just in case.

i have used it with success in the past , never had any ill side effects

John, I did the same, with same end result...lubeguard and mobil1, but she still feels the same.

transmission feels healthy, is always consistent, just not as it "should."

[Q45tech]

Sometimes you just wonder at the mental processes of humans:" looked at the fluid after a couple of days driving with that stuff... it seemed like it really thinned out the fluid."

ATF is roughly the viscosity of water at 174F. How can a THICKENER, a viscosity enhancer thin something?

Even the BG Conditioner works by thickening the ATF and swelling seals to help mitigate the wear and tear internal leaks.

[maxnix]

When one reads Q45tech's and TexasOil's erudite posts on friction modifiers (search on Lubeguard Black and Red), it is readily apparent that other than ATF itself, there is no need for any other additives as Wes has noted.

Just the product's name alone should scream "BOGUS!" to you. The fact they produce other inferior products should give you cause for alarm. Sometimes it's tough to learn there is not a magic pill or fluid.

correct me if im wrong but didnt you say that your shifts are smoother than before? if so can you tell me what youve done in chronological order to get it that way. do you still get that flat spot pause between some shifts? thanks for all replies

No John, after changing to Mobil 1 with a mechanical exchange it felt better than it did previously with regular ATF. Since then, I always feel a very slow 2-3 shift at mild acceleration (the flat spot you are talking about), and always a snap to 2nd gear, especially neck jerking when cold. When warm, still enough to be slightly uncomfortable.

I also have a sneaking suspicion that it may be a worn transmission mount, that is allowing the transmission to move just enough to feel it. Perhaps I'm wrong, but just a gut feeling.

[Haitian_King]

I used it last year. Can't say that it did anything dramatic, except to make a mess in my trunk. It was recommended to me by a member of this board who's highly respected and knowledgable. He wouldn't give me bad advice.

[JOHNQ]

well finally tried the lucas. i did another drain and fill with 3qts of mobil 1 and the lucas 500 mi ago and it definitely softened the shifts significantly.paranoidjack, might be worth to try it on yours if yours still getting those neck jerkin shifts. thanks all to those that assured me i wasnt going to harm the car by doing so!

But you really don't know that yet, do you?

If the transmission is functioning mechanically correctly, all you need is fresh ATF with the correct friction modifiers. If it is not, then nothing you pour in will repair it or benefit its functioning.

[NightRiderQ45]

I definitely agree with you but you contradicted yourself with the "benefit its functioning" statement. If this was the case, why put in friction modifiers if the transmission is shifting/operating normal?

To the OP, only 2qts. Did the Lucas stuff substitute for two quarts? I thought the drain and refill takes 4qts?

[ZMARKUS]

I use Lucas products in both my cars (99 Q45t & 2000 Lincoln Ls) with no problems. I use the Lucas Transmission addiditve in my Q45 t and although the trans was fine, it made it a bit smoother. I use Lucas oil stabilizer, power steering and fuel treatment in the Q as well.

[ZMARKUS]

i used lucas on all my cars when i 1st get them never had a problem

Same here

I think the Lucas stuff is two quarts. It's a pretty big bottle.

Or maybe he didn't get all of it out.

[JOHNQ]

yes it was 3qts of M1 and one lucas trans fix. i edited the other post also.to all the non-believers alls i can say is i bought the AE in FL in aug., trans was a little rough and had a flat spot in between shifts. did a drain and fill in Fl with 3 qts of M1 and 1 bottle of red lubegard and the trans felt the same. drove it to VA and did another drain and fill with 3 qts of M1 and 1 bottle of lucas trans fix and immeditely felt a difference. trans shifts are way softer and felt more cushioned than when i bought it.

[Mint Q45A]

Keep in mind that by doing the second drain and fill you also diluted more of the "old" fluid. By then you had more "fresh" fluid than before...althought the Lucas stuff may have helped...

[coolblaze03]

Not im my Q, but worked great in the 90 Chevy Caprice

[Fu Man Q]

I've had great experience w/ Lucas products.

I just bought a 95 Q w/ 154k in fantastic shape,( i guess i need to introduce her... thats for another thread tho, anyways...) having the car for only days, i did not had a chance to do anything but an oil change.

Sooo... Saturday night comes around and i get on it a couple times, no burnouts or doughnuts just smacking the gas at cruising speed. I know i let the kid inside come out. Then Sunday i realize something isn't right... Shift into "D" i press the gas, RPMs go up to 2k car is not moving hardly... OH ****e! I burnt my clutches up or my band or something is fugged up!OMG OMG!!

I didn't drive until last night to my bro's shop where i dropped the pan and replaced the filter and pan gasket. I noticed that the filter had a pea sized hole in the screen... hmm. Not any copper colored metal in the pan, but some nice accumulation of shavings on the magnet. After thorough cleaning and everything back in place, i refilled with 3.5 quarts Hi-Mi Castrol ATF and half a quart of LUCAS TRANS fix (whatever it's called). After cranking the car, (checking fluid level of course) holding the brake, i shifted thru all the gears a few times slowly, letting each gear set for a couple seconds. Backed of the ramp, put into drive and let the transmission spin by idle (giving no pedal) until i could feel some grabbing. Then gently accelerated. Once i went thru all gears and felt comfortable i drove around the blocks a few times, again GENTLY. It almost grabs the same! It shifts smoother, however there is a vibration that i don't believe was there before, but only having the car for a few days it may be pre existing. But there's no abnormal noise (at least noticable)!

Could it be the Lucas? Or just the fluid/filter change? I honestly believe the lucas helped, I know alot of folks don't believe in additives, in most cases i think they are right in the "snake oil" judgment, but in this case it may not be smoke and mirrors... cuz my new Q is running!

Guess you now know why the previous owner sold the car......once he got the $3000 estimate to replace the transmission, he dumped it before the transmission totally failed. Be prepared to replace the transmission soon, or throw a "for sale" sign in the window quickly.

[Fu Man Q]

Even though it sounds plausible, i really doubt that. The owner was in his early 60's and his wife just got an Acura RDX, and he drove a 2001 or so Frontier. When i asked the reason for selling, he told me of his wife's new car. I inquired as to the mechanical history of the car and basically all it ever received was PMs. He just recently replaced the AC compressor a few weeks back, and that was the most major thing the car has had done.

I know people do shady stuff sometimes, but i didn't get that from this guy. He seemed very honest, he even gave me the receipt w/ the most recent work(AC). He bought it as a program car w/ 20k on it from a dealer, then drove it for 130k before i got it. Hell i even got the window sticker w/ the $54k tag! The car has been well cared for over the years.

I don't want to sound naive, but i think it may have just been me abusing a car that never saw that kind of treatment?(and needed a transmission fluid change)
