I know the old 833 uses the threaded bras stop rings, but if they are slightly warn, and not sharp, they can accually slip on the blocker hub causing poor shifting, and grinding gears. Use the recomended old gunk.

Never put synthetic anything into something that was designed for real stuff. A. cause it will inexplicably leak like a sive, and B. cuase the sytnetic does not actually lubricate anything properly. Switch back to normal fluid ASAP (btw, this is exactly why all the newer mopar and chevy truck differentials have been suffering repeated sudden major parts failure, becuase they took axles they had been using for eyars and were designed for real gear oil, and one day decided to start using synthetic in them without changing anything else. )

Synthetic oils, gear lubes, trans fluids for the most part have better detergent packages than conventional fluids. If your motor, trans, rear end leaks after switching to synthetic fluids, you had a leak before it was just plugged up with all the junk found in conventional lubricants. Replace the seal. Synthetic lubricants are compatible with the various seal materials and will not cause the seals to shrink, crack or degrade. The lubricants should cause the seals to swell slightly to ensure continued proper sealing. Now the part about synthetic not be able to lubricate anything properly- where to start.... This could not be any further from the truth. Synthetic lubricants have very good anti wear additives in them to prevent metal to metal contact. They flow better than paraffin based lubricants. They remain stable over a wider temperature range. They have superior film strength. Here is a Study of automotive gear lubes. I'll put the proper synthetic lube in over a conventional lube any time.

I tried mtl and neither myself or the transmission liked it. I used to run the jeep manual trans lube which worked very well until a guy named Jamie Passon of Passon Performance came up with lube that works better than anything I tried over 90,000 miles and I have tried most gear lubes in there. But don't worry if you think I am bsing you 20 or more people will come on here and tell you works as well.

Redline pours right in fast. The dino juice takes FOREVER. I've never had a problem with gear clash with the Redline stuff. 833 or 435 trans. I want my fair share

Here are the results: Newly rebuilth a-833 with synthetic would need both hands to get out of gear, switched to mix of gear lube and auto trans oil and runs like a charm. My muncie 4 speed that had less then 1000 miles since rebuild (which was running excellent) also would need both hands to get out of gear. switched back to mix of gear lube and auto trans, now runs better but as been crunching gears from 1st to 2nd since i tried synthetic. Spoke to Passon at their booth in Carlisle after this experience and he explained to me why these older transmissions are not made to operate with synthetic. Forgot the details, but as something to do with sliders need friction to operate.

Similar to Automatics where the ATF needs to lubricate but also allow clutches and bands to grab, manual transmissions need a lubricant to keep the bearings and wear surfaces happy but also allow the blocker rings to grab the gear in order for a clean shift. Synthetic might be great for the actual gear contact area and ball/needle bearing life but not the best for syncro action and ATF might be great for syncro action but not the best for the bearings/gears. Its a balancing act. I don't see the harm in using the best lubricant that still offers good shifting quality but I wouldn't be afraid to back down to something more basic to get that proper shift operation. 2017 Contusion Blue Challenger T/A 392 M6 "BLKNBLU"
