Sluggish and the rpm's run at 2500 until i take my

Any codes?

change trans filter and fluid before inst. new fluid warm a bottle of lucas slip stop in a bucket of hot water (helps it enter the tran and mixing with other fluid) and fill. be carful not to over fill ( check with engine running and check frequently after change while trans is hot shift manualy from first to park holding it in each gear for three seconds to get an acurate reading) it does more damage to over fill a trans and power steering than to run it a little low. best of luck

you fill through the trans dipstick tube, use a funnel, put alittle in at a time and check till full. Van should be running while doing this. Also use the correct fluid recommended for this transmission.

I hope I'm wrong but I think your torque converter is failing. Sorry, Gary

Something is wrong with the torque convertor and or transmission. Make sure your trans fluid level is full.

If you have too much fluid it can lead to foaming. I would check that first.

sounds like your trans fluid is low, have your fluid level checked, whats happening is your fluid is going to one side of the trans , and not shifting until the fluid level returns to normal. you are probably two quarts low.

This is not good. It can be as simple as low or dirty fluid or as bad as a wornout valve body. If you know a reputable shop I would try to change the trans filter and put in new fluid.
There are some models that have a check valve under the filter so I am not advising doing it yourself.
The torque converter is your pump and it can be sluggish with dirty fluid and low rpm as you describe.
The simple maintenance may be all you need. Good Luck.

There is no dipstick on your auto trans. Checking it is a real PITA The trans pan has 2 plugs in it. The one on the very bottom is the drain. The one in the corner, up higher in a recess is the check/fill plug. To check, the engine must be warm and running, tranny in P. Remove the plug and fluid should dribble out. If it doesn't it's low, fill until it dribbles out, while engine is running. Obviously the truck must be on a lift or up on jackstands.

First of all, check your trans. fluid with the engine warm. You may only be low on trans. fluid. You can raise the car and do a trans. service. it's messy but doesn't cost alot to do. Just remove the trans pan slowly and allow the fluid to drain as you're removing the pan. Take the pan down and drain the pan and take alook of what's in the bottom of the pan. As long as you don't see metal shavings you're ok. You will see black graphite material which is the clutch materail's normal wear. Replace the filter and bolt the pan back on. Don't over tighten the bolts, just good and snug. Fill trans. back up, this should be about 4 qts of trans. fluid. Start and run, check for leaks and check to see if the trans. works better.
