My transmission is not shifting right at all and when I check the fluid level it is too high and really frothy. A few weeks ago there was no problems and the fluid level was right. So there cant be too much fluid in it, but the frothing is causing to seem like there is too much fluid. I thought ATF was supposed to be anti-foaming. would a transmission flush help this problem? how much do they cost?

Hi abbike18, hello All,


"Not shifting right" is not much to go on.


Low fluid level or clogged filter can also cause the same reaction. Have you've seen any sign of a trans leak?


Under normal circumstances, it is. Yours are not normal.


A "Trans flush" for any trans in any condition, will do much harm and no good.

At your skill/experience level, I suggest you take it to a reputable (usually a Mom and Pop) trans shop for a fluid and filter change. At that time they will accurately diagnose your problem and give you the price for its repair.

Hi Norm

My tranny has been acting up lately, and since thats one area where i pretty much dont know much about (Automatic transmissions blow me away on how complex they are). Anyways sometimes under hard acceleration it doesnt wanna shift from 2-3, feels like its in neutral, revs really fast, if i ease up on it it'll shift fine. Seems like it shifts early under normal driving. Also it has lag time finding the right downshift gear. And lately it doesnt even go to the right one, it goes down one gear when it should go down 2. Im thinking the TV cable, though i have to recheck the fluid when hot, i hate the dipstick design i have a feeling its inaccurate. I had a flush done last year, im gonna get a fluid and filter change done soon. Though i was reading and when u drop the pan only like 30% of the fluid gets changed, a flush pretty much changes it all. i was thinking about getting another flush, than in a week get a filter change and fill up to the lost fluid. Plan on using GM tranny fluid dextron i think its called.

Hi speedy266, All


Since I don't know anything about transsexuals, I cannot comment.


The objective is a filter change and inspection, not an oil change. If the fluid is so contaminated it needs to be changed, the trans is in need of a rebuild.

The reason I recommend having a trans specialist do the work, is, the diagnosis and repair can be done before the new fluid is added.


It's your time, your money, and your trans.

I always take my trans guy's advice. If he says it needs to be rebuilt, I buy the parts from him and rebuild it myself.


Sounds kinky.

Any fluid that meets or exceeds OEM specs will do the job.

I was a little low on fluid, topped her up, odd no leaks, transmission fluid is being burned through the vacume modulator, that explains the werid shifting. Also the harsh engadement from park to reverse and nutral to drive. Gonna replace, hoses, and vacumme modulator this weekend.

440T4 uses both tv cable and vacume modulator.
