So, I have finally gotten another chevy (my last one 10 years ago, an 87 s-10 blazer, didn't treat me so well). I was wondering if anyone knows about an option for upgrading the transmission solenoid on the 4l60e transmission. I just bough my 1996 suburban and the seller mentioned something about having done that. So, what is the solenoid on the transmission anyway? Have you ever heard of upgrading it to a corvette solenoid? I just want to get a bit of an education on the subject. Thanks in advance.
