2nd Transmission Filter Help!!!

[vanionBB]

I havent really noticed any flare ups in 2nd, I will look for them now though. I did look at the valve body when I dropped the pan, and I didnt notice any lose bolts, but I dont have an inch pound torque wrench so I couldnt really check.

Could I use a foot pound torque wrench on it? When I replaced the filter, I searched and couldnt find the torque specs for the valve body so I didnt mess with it.

I wish it would just set a code so I could know what the heck is going on...

On the bright side, after resinstalling the 2nd filter, flushing the transmission fluid (it was pretty dark but not burnt), and adding some Lucas Transmission stuff (looks like red molassas), the whine sound is slowly going away. I only really hear it when I gun it up past 3000 rpm's.

I think the fluid was shot and was causing the torque converter to slip at high rpm's. This caused a loss of power at high RPM's and the whine noise. With thicker? fluid, it grabs the torque converter better and transfers torque??

A torque wrench that is designed to work in the ft. lbs. range would work. Just remember that 1 ft. lb. is equal to 12 in. lbs. An example would be: 10 ft. lbs = 120 in. lbs. The Lucas stop leak swells the seals, and also expands when it starts to churn, and heat up.

this statement leads me to beleive that you do not have the correct fluid in your tranny, it uses the standard atf type for your vehicle, was the tranny stuff you added compatible? also what fluid are you running... this is an extreme example, but regular atf, will fry a chrysler tranny that is supposed to have a special chrysler only atf+3

Jimbo, my transmission is a 4R55E so I am running Dextron III Mercon fluid. I also put in 2 quarts of Valvoline Mercon V, 1 quart of TransX Transmission Slip Remover (didnt work), and 1 bottle of Lucas Transmission Slip Fixer stuff. The Lucas stuff seems to have worked pretty well, the whine noise is very slight now, only at 2800 to 3000 rpms and it is getting better the more I drive it.

The TransX stuff was a solvent based product, sort of smelled like carb cleaner. The Lucas stuff was THICK molassas consistency ATF (red) fluid. Both were safe for application on a Dextron III Mercon transmission.

I plan to change the external filter Monday and tear the old filter apart, I will post pics. I have a feeling there will be a lot of gunk in there. I will flush the tranny again this time completely with new fluid this week.

Brooklyn, I did sort of felt a surge into 2nd today. Maybe the valve body needs a new gasket... If I dont change it, will this hurt the transmission? I dont really have time or resources to drop the pan again unless it is very urgent. I think the hard parts are fine in the tranny and I dont want to damage them if I can help it.

Thanks again guys for all your input. Brooklyn, if I didnt have you I would be so screwed. You guys are keeping me on the road

Cheers!

I wouldn't mix 2 types of fluids. Refer to this thread for an application chart: http://www.explorerforum.com/forums/showthread.php?t=146841&highlight=transmission+fluid.

According to that chart, Mercon V is not recommended in your transmission.

Hey Marc, any news on your trans 'whine'?

I'm considering installing an external spin-on filter, and a search turned up this thread regarding yours.
