Hey guys,
Gonna change the ATF today. What's your recomendations? Brands? synthetic? Band adjustment? Let me know what you think.

Adjust the bands for sure. I'd put a synthetic in there myself but any high end fluid will do well.

I'd put a drain valve on the pan too - do you have the time to get one?

You will want to flush the TC too by unhooking the supply line TO the cooler on the front of the truck and bleeding off the old while filling new through the dip tube (as it idles in neutral of course). Hook a short section of hose to the cooler line you tapped into ( the one TO the cooler) and secure it to a good size tub. Otherwise you will have one major mess on your hands.
I taped a funnel to the dip tube and tally ho- took about 3-4 quarts or so to run clean.
Be sure to fill the tranny before doing this.

 

This is not ATF

 

guess I will have to start rereading from now on I missed the part about the bands, I was thinking 5speed.

 

Interesting. I asked that question of the local Dodge dealer service folks today. The mechanic said synthetic. The service manager said not with my tranny (75E maybe?). They both were emphatic about not doing a tranny flush. So I'm wondering too.

 

A tranny flush is not what I described, if that was your thinking. They hook it up to a machine that changes it out. They don't drop the pan do not change the filter, or get the stuff off the magnet etc.

 

Hello 8secondride, I had a local Dodge dealer to flush the automatic transmission, but I supplied the two 2-1/2 gallon bottles of AMSOIL Synthetic Transmission Fluid. They hooked up a machine to my tranny and poured the AMSOIL synthetic transmission fluid into the machine, so it flushed the old oil out of the torque converter. I could tell by the color change of the fluid that the transmission fluid had been changed, as it was a dark color when the flush was started and the new fluid was a more transparent red color. It has made a difference I'm sure, as I've just had a Banks PowerPack installed, which I ordered a transmission temperature gauge, and this gauge takes a while to register, but hardly gets over 170 degrees and only does this at an idle. Also, this was in 90 degree weather, in Jacksonville FL and driving back up Interstate 95 into South Georgia. If you need a source to purchase this fluid, contact me at my email address and I will be happy to send information. Myself, I changed all of the fluids out including the air and oil filter. The new air filter from AMSOIL uses new technology, a nanotechnology which filters better than anything else I've found and can be cleaned and used again.

 

I think I read somewhere they dont like to flush transmissions with lots of mileage because of the potential of damaging old seals, etc.

 

You are referring to a flushing method that uses solvents to clean out the tranny- bad idea.
Flushing the tranny with new fluid works well but doesn't replace dropping the pan.

Most all of the main diesel truck tranny builders caution not to adjust the bands unless you have slippage in 1st or R, you are likely to cause more harm than good.
I followed that advice and never adjusted my bands 212k miles.

 

Most shops will say if need to adjust the bands then you have bigger issues.
