I'd pay you to make me one

My trans got up to 132, was almost 70 out, is that hot?

 

[Hemi395]

Nah you're good. 185+ is when you need to start worrying IMO with the RFE transmission.

I've gotten to 210* on my trans before but I let it cool down when it got to that and have never gotten it that hot again. Still no side effects to this day.

210 ° WOW !

Was you towing , or climbing some serious mountains in the summer ?

Do you have the 6 speed auto 65RFE ?

 

[Hemi395]

Wow that's pretty hot for ATF+4! If it were me, I'd change that fluid...

Maybe someone in here can help me instead of posting a whole new thread. Sorry if this has been covered in here already but 37 pages is a lot to sort through.

I'm wanting to get my transmission serviced/ flushed I have just over 90k as far as I know its never been done. I would like to switch to Amsoil Transmission fluid since that is what I run for engine oil and have had great results. Does anyone have experience running their tranny fluid, and if so how do you like it?

According to the owners manual, the "normal service" interval for the trans fluid is 120k so you're good there as long as you haven't done too much heavy towing.

Amsoil MVATF is no doubt a great product. However I don't personally feel its a good fluid for these transmissions because they are so finicky about the type of fluid they have. Amsoil MVATF is a "one size fits all" kind of ATF and I prefer an ATF that is tailored for the ATF+4 specs. Castrol Transmax, Mobil, Pennzoil, and slew of others make a great ATF+4 thats Chrysler licensed. Keep in mind to be ATF+4, it has to be synthetic as per Chrysler specs. Here's a full list: Licensed Brands | Chrysler ATF+4® Licensing Program

Although not officially licensed by Chrysler, Redline C+ is probably about the best ATF+4 compliant fluid you can get.

Also, I would avoid a flush. Heard way too many stories of it ruining transmissions. Just do a pan drop and install a drain plug so you can do do easy fluid changes in the future. Or spend the money for a PML or MagHytec pan with a built in drain plug.

Thanks for the feed back, I have read a couple of things about people having trouble with a flush. How else would you be able to get all the fluid in the trans the same? Wouldn't there be some of the old fluid left in the torque converter?

There's 2 options. Install a drain plug in the pan, run the truck for 50 miles and do a drain and fill. Repeat as many times as you feel necessary. Second option, get two clean 5 gallon buckets, fill one with new fluid and leave the second empty. Unhook your cooler lines and feed the return line into the fluid filled bucket and the feed line into the empty bucket. Run the truck in neutral until the fluid is coming out bright red.

This is one of the main reasons I'm installing a Mag-Hytec pan is for the drain , I plan to do my DIY flush with 2 or three pan drain & refills with Redline C+ fluid after 500 -1000 miles maybe 1500 miles , hell who knows

Other reasons is the extra capacity , cooling finlets inside & out , drain plug and thick aluminum construction. ...not to mention they look realy cool.

 

[Backwoods]

is it as simple as dropping the pan and swapping the filters, or are there things that a shop has to adjust inside when you get a service done?

Simple drop & 2ea filter change . Install pan and refill .
No adustments required .

 

[Hemi395]

Shouldn't be any adjustments needed. There are 2 filters inside unlike most other transmissions, theres a spin on filter and the normal screen type filter. Most of us will recommend getting the Mopar filters.

 

[R.L.K.]

You can reduce the messiness of the pan drop If you have a small diameter tube with a vacume pump , something like this .



You can suck the pan out through the dip stick tube , this keeps you from dumping fluid while dropping the pan ....can't believe oem pans don't have drain plugs

Here is some temperature data after a 250 mile road trip. I took the photo at the top of a 1500 ft grade, cycling through gears 4, 5, and 6, maintaining roughly 70 MPH.

I'd have to say that the "partial fill" (8 quarts) of Redline C+, has really helped to keep temps down. Also, shifting was awesome and the 65RFE performed flawlessly.

Apologies for the glare.

Nice , glad to here the Redline is performing well for ya !

 

[Backwoods]

If I installed a Mag pan how much fluid would I need after changing the filters? Another thing, does anyone know how much HP a stock Tranny can hold?
