    I can only hope the 10L1000 ******* upgrade kit I purchased from the NexGen will do as they claim. I was showing another owner of the same transmission kit I purchased, as I had bookmarked it. And I find the kit now being offered had a new price and additional parts. They also had a PDF file of the current instructions, which I downloaded. There was never a downloadable file for my kit available. I compared the current instructions and the ones that came with my kit and found several new changes. So, I called NextGen and spoke with Will about the differences. He said he was not aware of the differences I had in question and told me he texted one of their engineers about my questions. He said the engineer said he would be in contact with me later in the day, about an hour or so, as he was busy with another matter. So how can I give them a referral with the lack of after purchase support. I will now copy the bold and highlighted from their instructions."Do you still have questions? Call and speak to a live technician at the listed number Ext. 1 We are here Monday through Friday, 8am to 4pm PST to support you in any way possible. Don't be afraid to let us know how we can help!" I did just that, so don't wait for them to get back with you after the sale.

    I spent nearly $5,000 with Next Gen Drivetrain and have been extremely disappointed with the customer service and post-sale support. After a torque converter issue, they denied the warranty, claiming my mechanic installed it incorrectly but they never provided any documentation or real explanation, despite promising to do so multiple times.I followed up repeatedly by phone and email, and no one would call me back including the general manager ***** whom I specifically asked to speak with. I left voicemails on May 27, June 3, 6, and 9, and even after finally speaking with someone on June 12, I only received an email saying my old torque converter (which I paid to have returned on May 22) was being shipped. It finally showed up June 14, nearly a month later, and still no one from leadership ever reached out to explain the situation or take responsibility.Ive bought parts from many major suppliers and they back their products no questions asked. Next *** made the sale and then disappeared, offering excuses instead of solutions. The lack of communication, accountability, and ethics has left me with a very bad experience. I would not recommend them based on how I was treated.
