Dallas Anderson uses Lucas Transmission Fix in '87 Audi 4000s (2.2L I-5, Auto)

First off, amazing product! I tell everyone about it.

Here's a little background, I needed a second car, because of a baby, our '96 Explorer just wasn't enough. So I picked up this Audi from an auction for $200. I put over $700 into it for repairs (all done myself) -- and I'm still not done.

I've heard these Audis can run almost forever, so I wanted a reliable second car. But about a month after I bought it, I found out that the seal between the final drive and the tranny has a leak. Crap! And after all this time and money into it already.

I wanted to keep the car because it handled great and was a fun car to drive, and I like the European "feel" of it. But I just did a complete overhaul on my Explorers Transmission in the spring; I didn't want to go through that again with this car.

This is how my tranny blew. While driving some "twisties" my tranny started to slip as if I put it in neutral after about an hour of hard driving. I pulled over and checked the level; it was low, so all I had in the car was a bottle of Lucas Transmission Oil. I added it and started to limp home. I had to stop and shut off the engine every 10 mins for about 30 sec., then I restarted the car, it would drive again. After 10 mins the tranny would start to slip again. So I had to shut off the engine, wait, restart and continue to drive. This cycling of on/off every 10 mins was how I drove the car to and from work everyday. I'd figure I'd just drive it till it broke, then buy another Audi. (This time for more than $200 ;-))

After about a week and the rest of the bottle of Lucas Oil in the transmission, the time between the on/off cycle times started getting longer. The tranny was getting better!

After another week or so of driving, the slipping has stopped. I have driven the car for almost an hour around town and it didn't slip once! Before your oil I couldn't drive longer than 15 mins until it started to slip.

Now I'm not sure if your Oil Treatment was the cause of this. But seeing how the Lucas Oil was the only thing added to the tranny in over two months, it has to be the cause of the tranny "fixing" itself.

Because of your tranny oil treatment, I have decided to keep my car and get the tranny fixed. Because of your oil I had more time to drive my "new" car and really fall in love with this little car. If I didn't add Lucas Oil to my tranny, I would have junked the car and bought some other beater. Your oil saved my car from the junkyard!

And for that I say THANKS you guys really have an amazing product. I just saw a commercial for your Fuel Treatment, AWESOME! I'm off to the store tomorrow to add it to my Audi. And pretty much any other additive you have on the market.

I have tried Slick 50, DuraLube, Engine Restore, etc. but none of them really seemed to do anything, but if your other products are half as good as your Transmission Oil Treatment, they would still be better than anything else I've tried.

Thanks again, sorry for such a long letter, it's just hard to describe how amazed I am that your oil treatment actually worked! And worked great!

Thanks, a new lifetime customer,

PS I received a quote to fix the transmission; it’s WAY cheaper than I thought. My Explorer cost $3200, so I was figuring around $1500, but it's only going to cost about $550! Thanks again to your oil treatment I can keep my car.
