Hot Rods Over filled transmission

I am having some issues with my transmission. My truck is hesitating from the transmission.. I checked the trans fluid yesterday and it was way above the full line. Will it cause permanent damage to over fill a transmission?

 

Yup.

 

I'll ask the obvious. I ***ume it was running on level ground when you checked? Warmed up?

Air bubbles from sloshing fluid are not good.

 

Might depend what kind of transmission it is? I'm guessing it's an automatic. But that's just a guess.

If you checked it with the engine running, and after moving the shifter thru the gears, and it's above the full line, then it will likely get air bubbles in the fluid, and may even push fluid out the vent tube when it gets hot. Not good.
And most auto transmissions need to have the pan dropped a little bit to remove fluid. Not fun, but not difficult, either.

 

Damage occurs when driving with aerated fluid. Usually can **** some out thru the fill tube.

Or you could get one of those oil change pumps for a boat and **** it out of the fill tube.

Sage advice. HRP

 

Or you can try pulling a cooler line and start it up. Put some hoses to catch the fluid. You'll get a qt out after a few seconds. It's quick.

I had to do this a few times when my ****** cooler went out and some coolant got in the fluid. After pulling the pan and changing the fluid I have been doing this periodically to try and get the all the coolant out.

 

Now that's thinkin,

 

Which of the cooler lines is output from trans?

 

Makes no diff

 

I can never remember. Always have to feel for heat, so am just asking which is output to cooler. It does make a difference.

 

It doesn't matter which one because no matter how carefully you place the drain bucket, it will make a mess.

bought onea these http://www.ebay.com/bhp/fluid-hand-pump 20 years ago or more -- absolutely EXCELLENT device -- use for engine oil ****** oil, coolant -- works GREAT!

NO mess at all

 

Haha. True.
I can't explain it but until I put a fitting and hose on both sides I always made a mess. I had heard that the fluid always runs uphill in the radiator but didn't want to say that earlier because a lot of top tank radiators have the lines side by side.
I got it down now.

 

Could put a piece of brake line into the fill tube with a piece of vacuum line drooped to below the pan, blow compressed air over the end and it will siphon out.

 

Pull the dipstick tube, if its to full it should pour outta there. Also a turkey baster in the hole will remove a qaurt pretty quick. Or just pull the pan and get one w a drain plug.

 

I've had to do this myself in the past.......as stated, disconnect the lines going to the radiator and turn the car over for a few seconds....check and repeat as needed.

 

good idea unless it a newer mopar because they have to be in gear or cooler circut isn't used!
