Trans Kleen Transmission Cleaner (#8009)

What does a transmission cleaner actually do?

Over the years, an automatic transmission collects dirt, sludge, and varnish the same way an engine does. Those deposits interfere with shifting and can show up as rough shifts, slipping, or a transmission that just feels tired. Trans Kleen #8009 is a concentrated cleaning solution that removes those deposits quickly and completely, so fresh fluid goes into a clean transmission instead of mixing with the old grime.

How do you use Trans Kleen?

Use it as part of a fluid exchange or as regular maintenance. Add it before the fluid change, let it circulate to loosen the deposits, then drain and refill. Doing it this way means the old fluid carries the loosened sludge out with it. It's an easy step to add to a service you were already doing.

When is it most worth doing?

Any time you're changing transmission fluid, and especially when you're bringing an older vehicle back to life. Vintage restorations are exactly where Trans Kleen earns its keep, because decades of varnish don't come out with a simple drain and fill.

Where can you buy Trans Kleen?

Trans Kleen Automatic Transmission Cleaner #8009 is available directly from Well Worth Products. Ships from our facility in Buffalo, NY.

Frequently asked questions

Will it fix rough shifting?

If deposits are the cause, cleaning them out makes a real difference. If the problem is worn internal parts, no cleaner will fix that. The honest play is to clean first, since it's the cheap answer, and see how the transmission behaves with fresh fluid.

Is it safe for older transmissions?

Yes. It's especially recommended for vintage vehicles, where deposits have had the longest time to build up.

What should I add after cleaning?

Trans Vital Transmission Conditioner is the follow-up. Clean first, then condition the fresh fluid to keep the transmission shifting smoothly.

Can I just do a fluid change without cleaning?

You can, but you're leaving the varnish behind and letting the new fluid dissolve it slowly on its own. Cleaning first gets the transmission to a known-good baseline.
