Review on πŸš™ Mishimoto Chevrolet/GMC Duramax 6.6 LBZ/LMM 2006-2010 Silver Transmission Cooler (MMTC-DMAX-06SL) by Steve Guillen

Revainrating 5 out of 5

Worth the money

2010 GMC Sierra 2500 6.6 with Allison 6 speed Definitely one of the biggest transcoolers out there. Installation was so easy using existing holes, it fit perfectly and was solid in its home. I'll update when I've worked for a while and see how it cools down. I did a fluid change using TranSynd and an external PSA filter. All servicing required 2.5 gallons of fluid with a large radiator and filter.
