Snake Oil that Worked: Lucas Transmission Fix
Monday, October 31st, 2005
While not directly Hot Rod related I figured that it merited a mention here on the site. My daily driver is a 1990 Toyota Corolla with an automatic 3-speed transmission. Over the course of the last 2 tanks of gas I have been experiencing transmission slippage that has greatly reduced my fuel mileage. This is a major problem considering that good fuel mileage is all that the Corolla has going for it. What do I do?

I spent some time with google looking up prices for transmission rebuild kits as well as possible common issues with the Corolla transmissions. My search proved helpful, but not in the way that I anticipated.
After a flurry of different websites offering rebuilds and replacements I came across the Lucas Oil homepage. I was brought to the site be a customer testimonial from John Quinn of Springfield, Illinois that stated:
I was driving down the street and the transmission starts slipping. Can’t get it past 10mph and then transmission just whines. Had it towed to shop and started looking for used trany. Saw your ad on the internet and tried a bottle. Not only did it drive without slipping, I’m getting about 40 extra miles per fill up at the gas station. Thanks a million.
Normally I do not fall for “testimonials” on a manufactures website, but at this point I am desperate. I simply cannot justify putting a new transmission into a car that I bough for $1000, so this morning I picked up a bottle of Lucas Transmission Fix from the local AutoZone. It set me back around $10.
The back of the bottle states “Results are Usually Immediate” so as soon as I exited the store I popped the hood on the trusty old Corolla and added half a bottle to the transmission via the dipstick tube. As directed by the Transmission Fix bottle I added the fluid with the engine warmed up and running.

I let the car sit and idle for a few minutes while I cleaned up, then took her for a road test.
Initial Impression:
Before I had even exited the parking lot I could tell the difference. The transmission was noticeably smoother on shifts and I could no longer perceive any slippage. So far this stuff is working.
Long Term Results:
Nothing yet, but as I get some more time with the car I will update this article.
