Stay clear of GBox in Colorado.
They rebuilt my 915 trans and it blew 3rd gear after only one sprint and one enduro
less than a year after rebuild.
The trans leaked like a sieve when i got it back from them and their response was " this is common in
mag cased trans" [ which it is due to soft compound -which is true ].
It seeped from the previous builders' work but not as bad as it did after Gbox.
Get this, they took my $ 7700.00 and their response is- it is a race car so there are no warranties.
What a racket. Charge race shop prices, pretend to be in the racing bund, and then claim no
responsibility when it is raced! hahaha
Stay away from these wannabe hacks and let's put them back in the lawnmower business where they
belong!
