Hmm..i guess definitely worth trying. My GTP also has a slow switchover from D to R, as soon as I press the accelerator it jumps like it's not shifted a few seconds later. Same with coming to a fast stop. I did find earlier this week though I think my trans has a little bit extra fluid than it should though, just barely above the max operating level and a few little air bubbles found. I'm guessing I'd have to siphon some out before adding the Lucas anyway too.
The Bonnie on the other hand...it's gotten to the point where you can turn the engine over and as soon as you shift to any gear it dies. We did have one moment when stranded with this issue where we started it, it was idling a bit rough, shifted it and it actually shifted without dying instantly but chugged for a few seconds before then dying. Everyone thinks the trans is toast, but that damn MAF sensor wire is still bothering me...my mom won't even drive the car anymore and it's sitting here while she gets a ride to and from work. I guess with good reason as she couldn't get it inspected either and it's past due a few months now...
I'm legit pretty depressed because I love that car to death and I know they all just want to get rid of it like it's trash for something that's most likely fixable... it just needs more time and money which my mom doesn't have..
