I can only speak from past experience as I haven't seen or talked with Jason in at least three years.
He started a business down here and was doing some great fab work. To give him the benefit of the doubt, and from conversations I had with him, he made some poor business/partner/financial decisions and came up short. As a result he left several customers hanging and, to put it lightly, didn't practice good communication skills.
To make matters worse he later set up shop at HardRock4x4, a place that is run by someone who is not so affectionately known in these parts as The Jeep Nazi. To say he is not highly thought of would be an understatement and Jason's reputation suffered further as a result..
Jason is a very nice guy, great fab skills, but as a business person (and as a psuedo-member of the Jeep community) he has been lacking.
I wonder not only why he is now in Tijuana, apparently doing business, but more importantly, what is the supply source for what I assume is a Jeep trans in Tijuana?
Personally I would not buy anything Jeep-related from TJ. Far too many Jeeps are stolen in SD and elsewhere and stripped in TJ for me to take a chance on supporting that trade. For all I know that may be Bransfords tranny
On a side-note, what kind of trans are you after?
