Quick and clean. Had a hand railing that I was installing in my house powder coated through SDP with amazing work done in a timely matter. Attached some photos. Quick turn around time with no issues noted.

Scott and his whole team went above and beyond with communication and attention to detail. Definitely the best shop I have ever done business with!

I got a built transmission back in October for my LLY Duramax. I put around 3000 miles on it and it is absolutely amazing.I didn't get the core refund back until February because they were switching builders and were behind on the core inspections. However, I budgeted this out and acted as if I didn't really need the core refund. A core charge shouldn't break your bank and YOU WILL get it back with a good core.Besides that, their customer service is excellent and they are always willing to help, and not even just for transmissions. Brandon answered some of my questions completely unrelated to the transmission with professional opinion and saved me quite a bit of money in the long run.If you are looking for a transmission build, get it from these guys. These guys are awesome, out of 5 possible shops that was looking for in builds, this is the one I chose. Customer Service, price and quality are unmatched.

Scott and his team went above and beyond to help us out. Showed up on Sunday to start our vacation when the check engine light came on. After a half day of calling around, they were the only shop that would look at our truck. Turns out we needed a new turbo. Scott squeezed us in because we were leaving Saturday. Needless to say, two long days and our truck was done. They only deal with new parts only. Thank you, Scott. You have an awesome team

I give them 2 stars because the transmission its self is great. My experience with my core refund to almost a month. I had to reach out to the company to inform them my core was sitting at there facility for 10 days. They told me they had new people in shipping and they would get to inspecting it some time next week. That's poor customer service.Then I had to reach out again 10 days later for an update to find out that the core had damages and they stopped the inspection process. I sent them pictures of the damages up front to avoid this situation. I have asked to be contacted by a manager and 20 days later still no contact.Then finally I just got updated that they are not going to uphold the quote they told me on the damaged core that they took an additional $50. So you hold my money up for an extra 3 weeks and then just pour salt on the wound by taking an additional $50 instead of trying to right your wrong. I think after spending over $8000 with your company I would receive better customer service than this.I had 10 more transmissions lined up from our company but we will be taking our business else where.

Ordered a rebuild on one of my employee s Allison transmission and got it back with issues. The issue was able to be fixed at our shop with the permission from Scott. As busy as Scott is, he reached out and took car of us. They do great work and their communication has been lacking in the passed but I know it will improve. Will do business with them again.

SDP is a great Diesel Performance shop. I blew my transmission and gave Scott (owner) a call and he set me up with a great built transmission. All the work was done on time and the shipping was on schedule. He s very good with communication. He replied to every one of my emails and always returned my calls. If you ever need any work done to your diesel or even if you need to order performance parts, Scremin Diesel Performance is the way to go!

HORRIBLE customer service!!!!!!!!! I gave them one star because giving zero wasn t an option! My husband and myself have called multiple times, left messages, emails and have not received any calls back! My husbands turbo was suppose to be done months ago! Every time he has been able to talk to Scott he was told it s done and waiting to be powder coated and it won t be long! Still nothing and that was 2 months ago! This has not been done in a timely manner nor professional at all!!!!!! I understand people are behind or having trouble finding help but we have been very patient and understanding for the first couple of months but now completely lying about timing and not returning phone calls is NOT ok! My husband has even emailed that we needed the turbo back ASAP even if it was not powder coated so he can at least race and still nothing! This is beyond ridiculous!

I have worked with SDP for almost 10 years and they have always been great to deal with. I've had several Duramax trucks over the years and a custom C20 Duramax swap that SDP has helped source custom parts for, as well as tons of insightful knowledge. They have always gone above and beyond when ordering parts especially throughout the very recent supply chain shortages. They've always stood behind their products and I would recommend to anyone looking for a top notch Duramax/Allison specialist company.

I called these guys to get my transmission looked at (Allison 1000) and to go through my truck (2005 Chevrolet Silverado 2500 LT) and look for anything they could find wrong. Transmission had some issues with slipping and getting locked up in 3rd gear and not shifting up or down forcing me to manually shift it until it returns to normal. I made the decision to just get it rebuilt, so my family and I would never have to worry about anything. Everything got fixed that were minor issues and the transmission is amazing. These guys are very busy people, very hard to get ahold of, but if you have the patience and aren't worried about calling them several times, I highly recommend their work, no one can beat their quality for the price. I will be returning to them in the future for more things, and my friends will know about their work as well. Well worth the wait. Thank you SDP for doing an amazing job on my truck and transmission.

Ordered a s400 kit from here. Just want to say the quality was top notch. I waited awhile for it to arrive but it was so worth the wait. Everything fit perfect, the y-bridge was so much nicer than my previous one from hsp, powder coat was great , customer service was awesome . ! Thanks guys !!!

I purchased a Built SDP transmission over 2 years ago and it s been flawless ever since, Now I am back to buy a compound turbo kit for my built motor that is going in soon and Scott(Owner) has been a Huge help with all of my questions. I highly recommend SDP if you own a Duramax and you prefer Quality parts and Great Customer Service.

Scott and the team at SDP are top notch, they are very knowledgeable and helpful. I love the way my LBZ drives after having the transmission built!

My turbo went out. So I called Scott an he hooked it up with a new turbo. After talking with him for about an hour on the phone we came up with the 68mm picked a color an in two weeks I had it dropped off at my door. I just so happen to live close to the shop they have. Two weeks after install I did a Trans shift kit they had it back to me in about 4 hrs. Two weeks later my tcm went out an I dropped it of at there shop an in about a day later they it figured out because when I dropped it off we did not know what was wrong. I am extremely happy with how they do business.

Absolutely worst customer service I've ever had!! No communication skills when it comes to keeping in contact with customers. Multiple times called with no answer during business hours or return phone call after left message. Parts not installed that I spoke with owner about multiple times. I do not suggest them for any mechanic work to be done on your truck.

Terrible customer service. Sold a problematic transmission, spent $10k and they didn't respond to a single call or email. BAD customer service.
