Lucas Transmission Fix

So I got my transmission pan dropped, all the parts cleaned, new filter and filled that baby back up with ATF (not me the shop) , and because of the 170k on my jeep some told me to pour a bottle of Lucas Transmission Fix - in it to maintain and renew some of the worn bands and lube the valves... Been looking online there is mixed opinions about this product some say "It clogs up the filter because of its thickness" - others said "That gooey stuff was all over the bottom of the pan" and some people said it works great and it fixed their problem.... Has anyone used this stuff?

well i used it on my old car an eclipse it shouldnt be used regulary,and yea its the thickest out there.it's used so the moving compents in your engine or tranny have less strain on each other when they rub agiaist each other.hope that made sense.not sure about anything else.its good to use for a soon to be or bad engine or tranny running.

Personally I would never change out the filter/fluid on a tranny with nearly 200k miles unless it had always been done as regularly scheduled maintenance. By this point, a lot of that slop you see in there is what is holding it all together. Cleaning it all out at this point is just speeding up the inevitable.

yup this too,if someone or you went ahead and changed the oil ,it will speed up the inevitable thus making you use lucas after that choice.

I have two friends that
swear by it and seafoam,both have said if they have a trans
apart [they buy and sell cars after fixing them]
they always add Lucas
also treat engine with seafoam

I dont keep cars very long 1-2years maybe
my last 3 I have done this too but only once right when bought and loved it
straight 6 and 2 v8s

I am not a big auto trans fan but on older 140,000 +trans
it does tighten up the shifting but doesn't do miracles


Ps Dont over fill ,you can just add but you need to take some out
or wait till your next fill

On my T/A that evry 12,000
I do it every year

Well I think that I'm not gonna use it, basically if the tranny is ok Im not gonna mess with it, If I feel like its gonna go Maybe a pour a bottle in there.

As far as changing the filter/fluid most places just drain your ATF and refill it not giving a crap about all the crap thats in there, thats when all the loose stuff comes out and wonders around the new fluid eventually causing problems. I've did this before on my Jeep Laredo 170k with the same mechanic now it has 190k, this guy is a family friend a mechanic for 35 years he claims that if you clean out all the parts and make sure there is no metal shavings or other crap in there and check for worn or demaged parts you should have no prob when refilling it. My Tranny was starting to slip before and act weird and now it solved most of the problems but one (maybe this has nothing to do with the tranny) but when the car is cold for the first quarter mile or so it hesitates lagging to go any faster, but after it warms up its perfect

this not changing tranny fluid is basically an old wives tale. it may have been true in the 80's or something, but i've been in the industry for 10 years now, and everyone agrees to change the fluid. and i nor anyone i've ever met has seen first hand having a trans go bad from servicing it.

its agreed now that changing it will help it last. and if its on its way out, its worth servicing it. i have serviced trans that were starting to slip w/ hi mileage, and they were fixed. if its on its way out it has a chance of fixing it, and if not, the trans is no good anyway. so its worth it to try even if its slipping.

so if its not acting up, the chances of it going bad from changing the fluid at high mileage is rediculously slim.

I actually worked for my mechanic for 2 years when he was doing contracting building houses and etc... now with the economy bad he went back to his shop and I was thrilled because now he does all my cars and when it comes to his advice I completely trust him he owns his shop since he was 20 years old he is now 55, come on you gotta give the guy some credit.

I Actually mentioned to him "you sure we should change the atf? I read online that you shouldnt on high mileage cars." He got kind of angry about how people actually believe that Not changing the fluid is actually good thing on high Mileage cars, so just screw it and let it go as far as it goes... he went on and on about it... Well anyway I'll be around and if my tranny ever goes I'll let you guys know. My ATF was changed for the first time at 170k and some people think that was the wrong choice but I'll stand by it =)

The transmission shop I use would beg to differ with you, along with the other 3 seperate shops I went to for differing opinions.

They all agreed had the vehicle had any type of regular maintenance or fluid/filter changes, that it would not be the case. Only one of those shops would do the job. The rest said it wasnt worth the $50 for the filter to do the job.

Tell ya'll what... The pump in mine is starting to get a little weak and slipping some times. You guys pitch in the cost to change it out and I'll be the ginny pig to see if it works or goes full on bad.

this is the consensus for reputable shops these days. and the myth sticks around and people will keep saying it. but ask them how many they've serviced lately that went bad.

i can think of one, customer came in and said the transmission wasn't right since someone serviced the it. someone serviced and didn't put the filter on right, once i put the filter on right, it was fine

So I came across this online at a consumer guide website and kinda related to this problem take a look

"If the transmission won't upshift for about the first quarter mile in cool weather, it is probably due to defective cast-iron seal rings in the governor drive."

Whats the governor drive? and do you guys thinkj thats the problem? My Jeep only seems to move along and not lag only after I drive the first quarter mile - only happens in cool weather - the guy that I bought it from told me that it always been like that in the winter, it was kind of a turn off when I drove the jeep at first, but then after driving it was alright so it didnt bother me.

let it warm up before you go. i believe changing fluid is a good thing. metal parts, and friction plates do not have a mental awarness...meaning they are just metal or composits. they do not get "bad moods" they are hunks of minerals formed into a shape. provided they are not broke, they WILL continue to work as they were designed to do. however,...if they are severly worn, then prudence would dictate to change them out with new ones. fluid DOES NOT HOLD OLD TRANS TOGETHER. thats silly. all those products are gimmics to sell to people that either dont want to face some facts, poor, or unwilling to do some work. half of those products will even progress the degridation of your component. gumming/galling/or plugging. dont be afraid of trans work...i think it easier than engine work. a simple overhaul of friction plates and seals is worth the hassle of a downed jeep for a week or so.

jeepersdoitdeeper...the pump is probably the easiest repair on a trans internals. and pretty cheap as well. i still attest that a slipping trans (other than simply to little fluid) is best delt with by cracking it open and fixing it proper. would you just fix your childs broken leg by giving him some kool-aid?
