Customer Ratings & Reviews

I'll never use anything else in my trans my shifting is so much smoother neutral is easy to find and clunking from shifting is much more quiet

Very impressed, smooth shifting, strongly recommend.

Great oil. Makes a big difference. Smoother shifts.

I was having shifting problems. Hard shifts and clunking. I was using Harley heavy synthetic fluid and I hated shifting the bike. I took the bike to Harley and they said it was normal but it was not to me. I changed to Amsoil transmission fluid and the shifting is night and day. I have the fluid in for 4K miles now and it shifts like new. I will never use anything else.

Very noticeable improvement in performance, smoother shifting, and it runs quieter as well.

After using this fluid in conjunction with the engine and primary fluid, my 15 HD Street Glide Special is running smoother than ever. I highly recommend you give it try.

Used severe gear prior to the transmission fluid which worked well but the tranny fluid seems to be even smoother and quieter and easily finds neutral with very little effort. Great job Amsoil!!!

Love the Amsoil in tranny, the"Harley clunk" when shifting is almost silent!!

Best tranny fluid for my twin cam

Been using for we'll over 80,000 miles, performs a lot cooler than harley oil

Great product

I jumped ship from HD products many years ago, started buying this when I could find it. Absolutely the finest trans fluid I’ve ever used, you’ll feel the difference the first time you run through the gears, and it has legs. If you get lazy & run longer than you should it still comes out surprisingly clean. I’m kind of ashamed of myself for taking so long to start buying straight from Amsoil 🤙

Immediately noticed that the typical Harley “clunk” when shifting fork Neutral into 1st was dramatically softened.

I use AMSOIL products exclusively in all my vehicles. I trust their superior products and the quality is second to none. Ordering is simple using the garage and delivery is usually in two days, sometimes one day. They are always offering free products with your order and orders over $100 are delivered for free. Can't say enough good things about the company or their products.

One of the best transmission fluid I’ve ever used.

Will always use Amsoil in my Harley

Neutral is easy to find, shifts smoother than any other brand.

I can’t say anything bad about this trans oil. I feel like the shifting is a bit smoother with AMSOIL

With Amsoil synthetic oils, everything runs cooler. Can’t beat their customer support and the value of their oil products for a Harley.

It was a good try it for the first time. Completely satisfied with the results. Shifts smoother and a more quiet gear noise.
