Hi, i have noticed only the 99 tls have the trans cooler in the rad. i know they have a kinda heat exchanger, but could u add an after market trans cooler in front on the radiator and tap the one trans line on top the trans? is there a reason they didnt put a cooler on these? i think the failure rate may be lowe rif they cooled better, but if im going to mess up the line pressures it would help.
