transmission
1997 GMC 1500 conversion van 350 engine 56000 miles. transmission kind of jerks when it goes into first gear, feels like someone bumped you in the rear. it only does this the first time it changes gears and it doesn't always do it. we first noticed this a few days ago.

ONLY DO A TRANSMISSION SERVICE IF IT HAS BEEN DONE REGULALY, IF NOT DONE AT SUGGESTED MILES IT COULD DO MORE HARM, (IT COULD) WE HAVE FOUND THAT TRANSMETIC ALSO WORK WELL. IT COULD TAKE A COUPLE OF DAYS TO START WORKING, BUT NEVER FOUND IT TO DO HARM. BUT YOU SHOULD ALWAYS KEEP UP ON TRANSMISSION SERVICES!!
GOOD LUCK

Your trans fluid should be red to light brown if so change it.It should not be pink that indicates coolant in the transmission and you would need an overhaul and the cooler replaced.Coolant deteriates the internal rubber seals and can cause clutch plates in the trans to separate.If this is a morning only problem it may be what is known as converter drainback.If it is I would not worry as drainback does not damage the trans as long as you wait until the gear engages.I almost forgot if its dark brown fluid your taking your chances.
