Great experience so far

Shipped within timeline that was given!
Instructions are spot on for installation and transmission runs smoothly overall great experience

2017 Silverado 6L80 xmission overheated

purchased new, never liked the shifting, 95k miles, overheated on the highway had to get towed home. added thermal bypass, had fluid flushed at dealer. truck was shifting hard and sloppy with lots of torque converter shudder on the way home. did not drive it afterwards. took a chance it was just the torque converter and purchased stock 1600rpm, went for a drive today and it was so smooth and shifted so well, temps are in the 160's. thank you Monster for the advice on the phone and having the parts I needed available and on sale. I am very happy all around.

Replacing my malfunctioning Ram transmission

Ordered and received the transmission within a week. Installation by my shop went smoothly, but had to work out the tune after a couple of days of driving. All good now. Scheduling the core return was also easy. Great price and included the fluid.

Great add on product

This product solved all my TV cable tension issues. Transmission shifts at correct speeds and cable doesn't over stress.

Excellent customer service transmission was built and delivered in a timely manner getting ready to install shortly

Best transmission ever

This is the most reliable transmission I ever bought

1995 4L60E 4x4

Transmission arrived on a pallet with no damage. Packed to perfection. I only had one issue with this project, the transmission pan wasn't for a 1995, it had a weird tab that got in the way of my shifter linkage....so I cut the tab off and filed it out smooth. I am very pleased with the performance of the transmission. I'll never use anyone else again. This was my second one from them.

Little Sexy Rides Again!

The old one out was easy-ish enough. Fair bit more colorful language with the new going back in. That is more of a Ford & I issue than the trans itself. Don't forget to get a new cooler if you want your warranty to be valid! Erased the old learned pattern from the ECU. 1 trip with adaptive 20 mile shake down and put that to bed. Running in with the adaptive learning turned off produced tight, smooth shifts. No jumping gears no unloading the turbos produced an excellent positive feeling ride. Will be loading the toy hauler and heading out to escape the relatives for Turkey day. If an update is required after dragging 8,780 lbs over the pass, I will do so.

Fast service

Delivered on time according to tracking , excellent service

Best billet converter

Well built, good warranty , nice to deal with.

Excellent customer service.

Great customer service, excellent pricing. Financing options available. Overall a very good experience.

BUILT 4L65E SPORT MONSTER

I've gone through 2 "Built Transmissions" in 1.5 yrs from a local shop. First one lost all gears except 1st, second one lost 3-4 and I wasn't nearly as hard on it as the first. So, purchased from Monster and so far (still in the 500 mile breakin) it's GREAT! I can feel the internals while driving unlike a stock unit. Ya'll know what I mean. I don't think I'll be buying from local shops anymore!!

fluid seemed good

saved on shipping buying fluid through them

2006 ram transmission

supper happy with the product and service. when I originally put my order in I used the wrong shipping address. I called and emailed them after hours and the next morning they called me back and got my order changed. They also ran through my vehicle with me to make sure I had ordered the proper transmission. The transmission arrived quickly and as expected. was installed easily and now the other core is on its way back

4L60E

Almost immediately after I placed the order, I was contacted by Monster to ensure the specs were accurate. The transmission was packed with care, exactly what I ordered and bolted in nicely.

happy customer

delivered in the time frame that was expected, no damage in shipping good create. this is the second trans i got from them, have no complaints
