you can rebuild your 4L65/60 so it can take higher horsepower and towing . a good transmission shop can set you up for just under $2300.00 installed with a transgo kit and hd parts kit a new hp torque converter and a cooler .
the trick is finding an honest trans shop that knows what they are doing . a stock rebuild with converter runs about $1600.00. FYI a stock trans shoul go at least 100000 miles if serviced proerly . a trans cooler should always be added. if your in Calli get Mike at Inglewood transmission to do your trans ,he is the man for HP/Tow transmissions.
