I put this oil in my transmission that I got from you. checked it a while back and it had a blackness to it. So I ordered some more oil, just got it today. The transmission is still going good. I will change the oil and filter soon as I get the filter.

Everything so far has been great. Service is awesome and delivery was way sooner than expected. I’ve got it installed but I’ve gotta get the computers reset before I can judge the build quality.

I had the transmission fluid in a very timely manner.

The title explains it all! Thanks guys!

Monster were great called the same day I ordered it, shipped fast and delivered 2000 miles in 4 days. Cant wait to get into the truck.

Thanks Monster for a great deal.

Received faster than expected installed in a 69 c10 it shifts nice!

Great experience, great Customer service. Always best to run the fluid Monster Transmission recommends for your build!

Its what was recommended for my transmission. Seems decent.

The transmission came in pretty quick and so far everything seems to be working as it should. My truck is back to shifting smooth and solid again with no shudder!

First time buyer. Awesome experience, products, fast delivery and easy return. What more could you ask for. Thank you Monster transmission.

Great customer service. Any questions got answered immediately. Very helpful

Noticed improvement over OEM transmission shifting, slight mpg improvement, this is a boosted f150 so gas mileage is never great

We have used several on our company sales vehicles & several @ my diesel shop NO ISSUES!

Monster Transmission is the best company to work with on a replacement transmission. They will make sure you have all the parts needed to make the conversion for any project you have.

Great staff and service they helped me get exactly what I needed to get transmission change and shipping was quick

Best transmission for the money

This fluid is not just any fluid buy its the only fluid I would run. Plus it's always best to run the transmission fluid the company building the transmission recommends.

Just installed a Monster 4L65E from Monster and it runs smooth. It's nice to have my Truck back on the road and with full power again. Shifts smooth and has zero discrepancies. Thank you Monster for a great product. Monster made this a simple task. Shipped right to my installer for me.

I have a 1963 Chevy II Nova SS Convertible that I LS. After doing a Brake Stand I Grenaded my 4L60E. I call up the kind folks at Monster Transmission and they hooked me up with a 4L65E Rated for 600 HP. Transmission is in route but Monster Transmission made this transaction Super Easy. Definitely recommend to anyone who is looking for a Quality Transmission with Great Service behind its Name. Thank you Monster Transmission.

Recently purchased a transmission and haven’t had any issues and the customer service was top notch

I received my 4l65e complete rebuild kit and boy let me tell you... It didn't disappoint. Best upgrade kit on the market. I'll definitely be spreading the word about Monster transmissions!

Fits well

Pretty excited for the transmission, will put it in very soon and have a update.

The sales rep was very helpful to get exactly what I need

Great
