how much is it for a trans do you know?

 

Was the transmission shifting correctly before the so called fluid change?

 

 

yes sir it was

 

It's your car and you can do as you please with it. If you are not able to check the fluid level yourself, I recommend you have someone other that the location that did the fluid change check the level. BTW, you may want to have it towed to prevent further damage.

Lucas, Marvel Mystery Oil, and others of their ilk are the very definition of snake oil.
Remember Slick 50? Their marketing was excellent, I swore by it myself until the data from the FTC showed that it didn't live up to the claims.
If you want to accurately evaluate any additive look at the specific, objective claim being made. Then test that claim.
Today's snake oils make claims that are vague enough they can typically say any test they failed didn't test the right way or thing. It's just marketing puffery.

 

I’ve never had to deal with one on a C5 but it will be in the thousands. Probably best to get a professional opinion and quote from a shop if trans fluid isn’t the fix.

 

chat is this legit?

 

As I stated, it isn't a miracle worker, but it has the potential to make a difference. I remember Slick 50 as well. Fell into that one as you did. Used Rislone (remember that one) at every oil change for years, finally broke free from that one.

Going out on a limb and saying I've had more experience with these products that you have. I've used several products over the years. I can' tell you how many cars I've drive over the past 3 decades that I've put to scrap. I've put 300k miles on more cars that I can honestly remember. Transmissions and brakes are second nature. I can change brake pads as fast as an oil change. I'll say it again, Lucas is not snake oil. It also isn't rebuild in a can. It has, and can, make a difference. Never seen it stop leaks or turn a beyond hope slipping transmission into a trailer hauler, but I have seen it tighten things up. Not across the board, but it is an effective product and has it's place. It's worth a shot. Gotta buy new fluid anyway, spend an extra $10 on this and keep your fingers crossed.

 

Should I buy a used trans or rebuild the one I have?

 

I'd take it to a local transmission shop.

 

This can't be legit. If it is, you guys showed up to the party 15 years too late

 

You probably have used various snake oils more than I have. "Fool me once, shame on you, fool me twice, shame on me."
Repeating your same claim that "it works" doesn't make it any more true the third+ time than it was the first time.
If you want to convince a future reader you'll need to clearly state an objectively testable property the snake oil claims to fix, show that the snake oil actually changes that property in the way you say it does, and show that such a change is beneficial in the way the snake oil says it is.
Until then it's just marketers doing their job of separating you from your money.

 

I've seen that account post similar things for newer corvettes, I think the account is legit. I have never personally interacted with them.
It's worth a shot. I wouldn't provide any personal information in the first email but it won't hurt to check them out.

 

welcome though

 

Lucas is not snake oil. It isn't rebuild in a can, but it CAN help. I've driven several hundreds of thousands of miles for the USPS in my own vehicle over the years. Seen at least one transmission problem over the years that I can recall.. Lucas can buy you time, or I've had it keep things going. Doesn't rebuild the trans, but I've seen it make a difference in transmission and power steering pumps. I've also seen it do nothing. At $20 its not going to hurt.

If I repeat this again will it become any more or less true? You want me to give you scientific evidence, which I will not even attempt to do wasting my time but a 60 second cursory search yielded plenty of reviews online. So here's a thought. I've used the product several times. I'm a rural mail carrier with 27 years service driving my own vehicles through the worst conditions ranging from -40F wind chills to 106F heat. 100+ miles per day on roads NYC taxi cab drivers would love to have. As stated I've driven several hundreds of thousands of miles in my career. I KNOW a thing or two about keeping cars running on my own dime. I'm telling you Lucas has an intended purpose I'v,e used it, and it has worked. You on the other hand have never used it, call it snake oil, and are now calling me a liar without any first hand experience. I'm trying to help the OP, you want to throw barbs out there and call another CF member a liar over a product you have zero experience with, then demand I search the internet to give you scientific evidence. Here's a though, why don't you spend your time proving to us a product you've never used, never bought, have no experience with, doesn't work because you don't like the idea? Until then, go pound sand. One doesn't have to look hard to find anything another doesn't have first hand knowledge of. To use that lack of experience and impose a baseless opinion as truth is both incredibly naive and displays an obvious attitude of self importance. I'm done here.

 

No one is saying you are lying. Clearly you believe your snake oil works.
As you pointed out, you can't provide scientific evidence that it's beneficial. That's not an accident. It's a feature of marketing puffery.
