Lucas Transmission Fix Oil

Not open for further replies.
It has worked wonders in a few transmissions, then again, I have had one fail just after changing the fluid/filter and adding some. I am undecided, but the trans temps were A LOT LOT COOLER with it installed.
 
I common "cure" (putting off the inevitable, really) for a slipping transmission is to add limited-slip differential additive.

I wonder if the Lucas stuff is the same or works on a similar principle?

So what is aprox the ratio of good vs bad experiences with Lucas Trans Fix? I'm thinking about putting some in my Chyrsler 3sp auto trans for a delayed shift problem when cold. Still a good idea?
 
I would go with the Lubegard first. That Lucas stuff is really thick, I don't know if it would help much with Cold-Weather performance.

You can get the Lubegard at Pepboys or Autozone sold under the AAMCO name.

It depends on what is wrong with the transmission.
If nothing, why bother with anything?
If the tranny is acting up, a new filter and fluid change should be the 1st thing to do.

Because lucas trans fix is thick, I'm guessing that it would help trassmissions that have seriously sheared down the fluid, for those who don't want to change the ATF regularly.
Also, lucas is pretty good at stopping seal leaks.
If your transmission is acting up because of 'sealing issues', then it might help.
 
Here in Calgary, Canada we don't have pepboys or autozone, but I'll try and look for that lube guard. The thickness of the lucas is only when it is in the bottle, but shouldn't it mix with the tranny fluid and become thinner?
 
If you have a problem with a tranny JUST GET IT FIXED. If the tranny is just serviced or is working fine I agree Lubegard is the best.
Having a tranny fail after a service is when many fail, the problem is most people don't service them enough. 20,000-25,000 miles between tranny services. People will waste time & money IMO changing oil & filters every 3000 miles but won't service there tranny until something acts wrong.
I worked in a Tranny Shop in the 70s in San Jose, Ca.I've seen most of it. I'm grateful that I can say I have never lost an automatic trans due to oil or slippage. I have blown a few racing mostly hard parts.
 
Just had the trans serviced with a new govener, filter, valve body cleaned, and fluid flush, but I still have the shifting problem when cold. 1st trans shop said I would need a rebuild if the service didn't work...cost me $365 for the service. The 2nd shop says that the seals, torque converter and pump are leaking, and I don't have the money for a rebuild. I'm going to give the Lucas a try since most comments say it will seal leaks.

Just wondering: year/make/model/maintenance history?????
and fluid brand/type used?
 
The car is a 1988 Chrysler Lebaron turbo, 3 sp auto, 173000KMs. Fluid type is whatever the tranny shop would have put it, I would assume they put in the correct fluid... Just bought the car couple of weeks ago, and the trans seemed ok at the time, but after driving for a week the problems started. The previous owner said that the car sat for a year, so maybe it was sitting because of the trans problem?!!?

Never assume that a tranny shop used the correct fluid. Make sure you have the correct or better fluid in that transmission.

Also, the bands need regular adjustment. Have the bands adjusted.
 
I've adjusted the front band, but the rear band is internal, the tranny shop says the bands are not the problem, although they didn't even want to adjust them. Rebuild or replace seems to be the mantra for the trans shops here!

Let us know if the Lucas works. That or something like the Slick 50 High Mileage Transmission additive might work. (sold at Walmart).

Yes, the Slick 50 High Mileage forumla is thick, like the Lucas Transmission Fix, and designed to stop leaks. Sold at Walmart.

Lucas seems to be a popular choice for Dying transmissions around here.
 
I put lucas in my transmission and noticed after awhile I was getting a delayed shift in second gear. I pumped out as much fluid as I could and replaced with Mobil 1 synth tranny fluid and problem has all but gone away. I have used Lucas in power steering pumps and it worked great, but will never put it in a tranny or engine again.

Hmm.. I think the recommended fluid type for your tranny is Dexron II, and that's probably what they put in, but I remember reading on the Allpar forums that a lot of people there seem to prefer using ATF+3 in their 3 speed automatics. Something about better shift quality due to one of those fluid types being more 'slippery' than the other. I suggest you post this question at allpar.com and see what they recommend for you.
