Sonnax 6L80, 6L90 Remanufactured TEHCMs for Top-Quality, Affordable Repairs

[@autonomous_collective]

Huge fan of the Sonnax TH400 products. Never been happier on the street and strip.

[@sonnax]

Awesome, thanks so much for the great feedback. We really appreciate your support!

Pretty much every unit that goes out my door. Has a Sonnax part in it. Glad to see an alternative to OEM with these TECHM's. GM is selling refurbished TECHM's as new ones now. At least with a new price tag. Hoping that Sonnax has these priced at a point that makes sense.

GM is NOT selling refurbished TEHCMs as new.

How do we purchase this if sonnax doesn’t sell direct to the consumer, I’m rebuilding my 6l80 now and went threw transtar for my parts which was a big mistake in my opinion.my bushings where completely different than what they sent me. I got no receipt or item list when shipped to me .I originally tried to order parts from the sonnax website and it stated they do not sell directly to the customer so is this video for certified shops only. And if other companies offer a send in your TCM and your info and vin they program it for you so you don’t have to get it hauled to a dealer or a shop. Do yall over that service

IF YOU REPLACE THIS ON YOUR CAR YOU MUST TOW IT TO THE DELAER TO PROGRAM IT TO YOUR CAR. People should know this important detail.

Hi, and thanks for your comment! If you click the link above to the part page on our website, it states that after installation, this remanufactured TEHCM must be reprogrammed on the vehicle using a J2534 device in order to function correctly. Thanks again, and have a great day!

​@@sonnax Can it be taken to the dealer separately and flashed, then installed?

Hi Have you guys given any thought to contaminated trans oil with metal particles interfering with electrical conductivity on the open type electrical terminals inside the box , wouldn’t this play havoc with computers with the oil no longer being a insulator?

[@sonnax]

Yes, we've considered the impact of contaminated transmission oil with metal particles on electrical conductivity, particularly regarding open-type electrical terminals inside the trans. While contamination is a concern, our investigations into various rebuilds from multiple shops show that the level of contamination required to significantly interfere with low voltage signals would have to be quite substantial. In typical transmissions, there is a magnet and a filter that will catch most of the problematic particles. The contamination levels observed are generally not high enough to cause notable issues with electrical conductivity or disrupt computer systems. If you see that amount of contamination, then there is likely a much bigger issue that needs to be addressed. Thanks for reaching out!

Can I buy this straight from Sonnax?

[@sonnax]

No, we are primarily an engineering and manufacturing company, and find it’s best to leave distribution to our expert partners. If you are having trouble locating a distributor, we are more than happy to help you with that. Feel free to contact us via email at [e-mail], or phone at [phone] or [phone]. Thanks for reaching out, and have a great day!
