I've got a 99 2.2 Cavalier with the 4T40 transmission. I'm intending to replace the leaking trans cooler lines and the associated seals. I'm not looking for a "how-to" or anything, more for help in tracking down, or fabricating the tools that GM calls for to remove and install those seals. I've found them online for about $200... more than it would cost to send it in to the dealer. GM calls for J41239-1 (installer) and J41239-2 (remover.) So, any of you experienced mechanics (or longtime JBO members) that have suggestions, please, let me know. The lines are seeping, and after 240K miles I'm concerned about one of them blowing out :-( Thanks.
