Constantly fails Constantly fails. Had to replace motor after motor. Who ever is building their engines sucks. Went thru 3 motors, the first two, over heating, head gasket failure. Third engine didn't even make it out of the shop, dead cylinder. Gave up sent the 4 engine back to sender, pulled the Third motor and built it my self. Waste of 4k for the motor and 4k+ for the installations. I would give a negative star, not a option.

Fast, professional service They were friendly, easy to deal with, know their products, and shipped product out a week sooner than estimated. Transfer case was like new. 5/5 experience.

STAY AWAY! WARRANTY IS A SHAM, Customer service is POOR! I purchased a rebuilt engine from them, The rear main seal failed within 500 mi they wouldn't cover the complete repair cost for labor which cost me an additional 100% labor. Their product was mediocre and their customer service is terrible. Support your product with a quality warranty and customer service or your warranty means nothing. Your product is inferior if it's failing in the break in period. Stay away! No supervisors to speak with, no attempt at making it right!

After a month of contemplating After a month of contemplating being skeptical about ordering an engine online, I finally did. It was a great decision. Customer service was quick to respond to all of my questions and concerns. And scheduling a core pick up simple and easy. I'm just finishing my break in process and my 2010 GMC SIERRA is running better than before. Thanks POWERTRAIN.

Good Easy ordering process. Able to get it taken care of on the phone right away no callbacks or inconveniences. Five week turnaround is a little bit long for my engine, but if it doesn’t go much past that it shouldn’t be too bad. Also, some immediate email notifications would be nice, so that I know my payment has been received and the Ball is rolling on getting the engine delivered. I also think you should have a little bit more than a 15 day turnaround for the core charge.
