I was considering doing this, but they said it would void the warranty on the parts they actually DO cover. Since I haven't even used the transmission yet, I feel like that would be foolhardy. For anyone considering Monster, keep in mind that their warranty does NOT cover shipping it back to them for repairs, unless you paid $800 up front for the "premium warranty".
I did some thinking and some calling around and there is a reputable welder/fabrication shop near me that specializes in this stuff that will do weld it for $65 an hour. The owner told me that it won't be any weaker than the unbroken parts of the case. I'm going to spend my money here instead of sending $1300 to Monster and waiting a month to receive another possibly-bad case.
Here's an excerpt from their Warranty agreement:
Limited WOWanty DOES NOT cover any of the following:
1. Any and all freight costs including freight damage claims.
2. Fluid, rental cars, loss of wages, any labor costs not associated with a previous agreement made by Monster Transmission & Performance.
3. Removal/reinstall fees, towing costs, diagnostic fees and any other incidental costs or damages which may be associated with product failure are not covered.
4. Any product that has been physically altered, improperly installed or maintained.
5. Any product used in an improper application, abused or not used in connection with the proper parts.
6. Any product that is defective due to accident, neglect or unauthorized repair.
7. Any product where proper cooling and or fluid levels have not been maintained.
8. Pump, pump components, shafts, sprags, drums, planetaries and/or cases. These parts are not commonly broken, however in the event this occurs, MTP offers replacement parts at a discounted price.
Number 8 would mean that they have NO incentive to send you a good part for any of those components. In fact, they have an incentive to send out a certain number of bad components from that list to ensure that some customers send them even MORE money to get them repaired. Assuming that they are not actively doing that, they still can treat those parts with complete indifference during Quality Assurance and inspections stages of the build with nothing to lose and a little more money to gain.
I have seen them on a few YouTube channels and TV Shows over the past few years. I would imagine if one of those folks called them up with a problem, they would be happy to fix it for free, and fast.
I will say this for them, the one person I dealt with during the sales process did email me back just now and tell me that she will discuss it with her leadership team to see what they can do about the high price.
I'll keep you updated on what they come back with. I'm still getting it welded tomorrow. If Monster comes back and says they'll put a brand new case on it for free or something, I'll send the welded one back to them and get the new free case, but I doubt that will happen.
