H3T 3.7L

  • Automatic transmission

YES IT ONLY TOOK LESS THAN 400 MILES AFTER WE OVERHAULED THE TRANSMISSION & INSTALLED A FACTORY RADIATOR & THERMOSTAT THAT THE TRANNY OIL COOLER RUPTURED AGAIN. WE HAVE TAKEN THE ORIGINAL COOLER APART TESTED IT WITH LOW AIR PRESSURE IN SOLVENT TO FIND OUT IT HAS A POOR CRIMP IN THE SEAMS. IN SO DOING ALL MY RESEARCH I FOUND THE ORIGINAL MANUFACTURE TO BE OF A CHINESE COMPANY. THE AUTO DEALERSHIP AND GM REFUSED TO PAY MY WARRANTY CLAIM.

I HAVE BEEN IN THE AUTO TRANSMISSION REPAIR BUSINESS FOR OVER 30 YEARS AND NEVER SEEN SO MUCH JUNK BEING MANUFACTURED . IF YOU ARE GOING TO SELL JUNK THEN YOU SHOULD STAND LIABLE FOR YOUR PRODUCT AND PAY FOUR MISTAKES. QUIT THROWING THE MONKEY ON OUR BACKS . WE WORK HARD FOR OUR LIVING AND LOOSE MONEY BECAUSE OF THE CHEAP PRODUCTS THAT YOU SELL. SO ALL YOU TRANNY GUYS & GIRLS BE AWARE OF THAT RADIATOR, IT WILL COST YOU MONEY IF YOU USE A OEM RADIATOR ON THIS H3T
