I just wanted to share a recent experience I had in phoenix az. I've been traveling from western ny to phoenix 4 about 5-6 yrs now during the winter (bootlegging some sun) my truck has 250k on it & I do tons of towing so I was thinking about having my tranny done @ some point but wasn't sure what I wanted.I had some wrk done on my truck in phoenix in the past & wasn't really happy with the service I got. I'm a construction guy not a mechanic, but I'm not stupid either so I know when I'm paying more than I should....I recently met a guy named Ben (D-Max Mafia) & he referred me to Chris @ S & K Allison...I saw the hp that Ben was producing knowing that it was @ least 300 more than I have & he said he's been trouble free 4 over 3 yrs doin burnouts & drag racing!!!! So I went & talked to chris & I gotta say it was a real pleasure...He spent time w/ me explaining what he found when he diagnosed the problem gave me some suggestions based on how much hp I have(inc. future power) how much towing I do etc &.He didn't try to sell me more than I needed!!super service, super happy!!!thanks Ben & thanks Chris!! What a blessing knowing that the job is done right @ fair price!!!! I got billet torque converter upgraded c1-c4 clutch packs new c5 packs new shift kit all 4 the same cost as a stock Allison re-tran!!!!IF your in & around phoenix go see Chris you won't b disappointed his # is 602-402-5797
