Not sure if mopar posi lube for differentials would help or be compatiable, but it is just a thought. I am probably way out in left field on this one, but it worked on a gear set I had changed out once, it howled I took it back to the repair shop and thats what the put in it and low and behold it went away. They said it adds to the lubricidity of the gear oil, maybe that would help the shifting.

 

I'm filling through the top bolt hole for the PTO cover.

Got you thanks, but if i remember correctly those are small bolts [1/4-5/16] are you pushing it though a small rubber line or something. thanks

 

Yep, I have a gear lube pump with a small fitting on the end.

I was running the standard fill level with amsoil mtf and had no problems running 30k intervals. I then decided to overfill by a quart and added through the top of the trans. Made shifting even smoother, but still a bear when cold. FYI, I could get 4.75 qts. in the trans with the truck on ramps to the one side.

 

Hey Stock600,
You're lucky having 60k and being on the first clutch. I was on #4 by then. The moron mechanics at ATS got grease on #2 and it trashed it (14k miles on that clutch), then #3 was in for 6 days because they put in a Ceramic disk when I had told them I was pulling........ #4 was a stock one till I could get a good one to stick in. I had to take the Bullydog program off while I was looking, the stock clutch wouldn't hold. From #4 on I am having someone else do the work. As for the leaks, I've had 3. With all the ins and outs, the seal between the tranny and t-case leaked. Or so I was told by ATS, DC and my new mechanic. The overfill was only about 1.5 qts, I was trying to make sure extra fluid got up in that back section of the tranny. What I did was use a hand pump through the normal fill plug and fast fingers to keep the extra from leaking out. That's a leftover talent from my Grease Monkey days in college.

 

I may just try that too, my leaks may all have been caused by the clutch thing I mentioned above.......
Mine is still shifting just about perfect, but it still has a gremmlin from time to time.

 

Has anyone ever tryed a lighter syn. oil like we ran in the getrags? Somewhere in the range of 30 w? Seems thiner oil would help in the shifting.

 

The factory fill is synthetic on these. I replaced my fluid with Penzoil Synchromesh, which is listed as a direct replacement (probably where Dodge gets it) and there is no difference. It shifts like a manual transmission, that hasn't changed in 130k miles. It doesn't do anything too weird in the cold, either. You guys are whiners!

Ok, I haven't driven a 6 spd Dodge. But I do know how to drive a truck; 9 spds, 10 spds, Super-10's, 13 spds, 4 on 4 Brownie boxs, etc. Does double clutching or maybe floating (no clutch, just syncing rpm's and gearing) each shift help? Seems to me it would. It's all a matter of everything mateing up just right. I know, truck trannys are non-syncro and Dodge's have syncro's, but maybe it would help................

 

I double clutch (blip the throttle between) downshifting when the tranny is cold. Easier on the synchronizer's.

The oem lubes works good in mine but only lasts 10k miles and it shifts bad again. Ams. MTF was OK but was too stiff when cold. I just put in RP Synchromax and it's doing the best - -shifts like butter and less gear rattle. It's at 4.5 qts. but I have enough to go to 6 qts someday. Craig

 

That's how I feel,my has Penz. and shifts great.

 

People remember those neg. comments when YOU have a question and are looking for help or advise. And C Schomer is that RP the same wieght as factory lube or lighter?

 

I double clutch/throttle blip all the time, downshifting. Floating gears will work but if you rush it, it gets very hard on the sycnros
