I didn’t flush the trans. I only drained what comes out after removing the pan plug. However, the trans fluid has been changed a few times in the past, most recently about two years ago by my mechanic. With the car approaching 100K, I plan to change the fluid more frequently than recommended. Eventually, I will learn how to do a complete flush.

Anyway, I drained about 1 gallon of fluid out, then replaced it with 1 gallon of Valvoline MaxLife DEX/MERC ATF, and added an 11 oz. can of BG ATC Plus. I’ve never used either of these products before, and wasn’t expecting any noticeable improvement of any kind.

After driving the car for a few days, it dawned on me that the shudder was gone.

Have you ever had a similar experience?

Hope it lasts for you but in reality those additives cause additional clutch slippage removing the "shudder" by causing the clutch to burn up.
94 were horrible transmissions with even worse converters.

I 100% agree on this, If you don't care about the car or destroying the transmission and just want the shudder to go away, I used friction modifier. I didn't drain any fluid and added half a bottle to my Mark VIII, shudder is completely gone...

It's not a permanent solution and I'm sure it did more harm than good, but my car has too many issues to justify paying a shop for a tranny flush:D

Are any of the additives safe to use?

For example, "Dr. Tranny's Instant Shudder Fixx" is mentioned in this article.

Are the additives safe to use? Yes. Are they necessary? No.

Just put Mercon V in it and call it a day.

I dont even use Mercon 5, I use fully synthtic fluid in all my vehicles and in customer vehicles I've never had to use the additives to fix shudder on a customers the new fluid usually does the trick

The fluid you use is basically the same as what I use and meets merconV specifications.

Shutter fix makes the fluid a bit slippery and treats the clutches. Lots of people who write reviews about it say how nice the tranny shifts after. What is does it makes everything smoother at the expense of heat and friction. It modifies the coefficient of static and kinetic friction. Think leaning your hand on wet surface, then adding a bit of soap. Much easier to slip, and there will not be any grabbing.

I've read that Ford limited slip additive works the same way. Not saying to use it, but in the mid 90s a shop owner I was friendly used it to used it to fix shudder in the taxis.


Sometimes fresh Mercon V does not fix the shutter. Beyond a misfire issue, the trans probably needs a new converter. I've seen those chemicals keep it going a few years though.

I know for a fact MANY trans shops here use lubegard red or black(black is to convert generic fluid). Anything by lubegard is very good stuff.

Lubeguard red is to prevent valves from sticking, Lubeguard black is to convert dex3 to chrysler 7176, lubeguard green converts dex 3 to mercon V.
