Ok so i was given a 99 se with a vulcan. The car shows 159.000 and it seems to be a bit neglected. It seems to have what i call a delay when puting it into reverse or drive but never hesitates to go. maybe like a 5 sec delay. When driving it shifts fine and no issues. I want to know if it would be a bad idea to change filter and fluid on trans and btw it is showing a P1744 code. I dont want to kill the trans by doing this but i guess if it does im not out the cost of the car since it was given to me. I know the car was bought new and owned by same family and passed down from father to daughter to son and thew car is getting ****** mpg not sure if that is from the need of a tune up or trans issues also.
