Are there any advantages to using synthetic 75w-90 in the rear differential? In fact, 10w40 is about the same consistency under thermal stress as 75w90 gear oil. Hard shifting, noise, wear, and internal binding are usually caused by lubricant issues — dirty gear oil, low levels, or the wrong lubricant. A standard 'dinosaur' crude-oil engine oil would likely meet this demand, however it would require too frequent a change interval to prevent sludging and oil breakdown for transmissions. The transmission had a clutch-starter interlock system to prevent the engine from starting while the clutch was engaged; it had a non-adjusting clutch pedal position switch on the clutch master cylinder push rod and was wired in series with the ignition switch and starter relay coil. I am not so well versed with gear lube so any info is very much appreciated. It took some time to find 1st gear to pull away from the stop light. It protects against rust, keeps seals soft for long life, and is compatible with brass synchros for smooth synchromesh shift quality.
Other leaks, where components meet, could be due to problems with the sealer or incorrect bolt tightening. Its internal components were also lighter, resulting in easier shifts and a total 100 lb weight savings. And where is the fill plug? Three different selectable snap rings were used in the constant-mesh transmission; they adjusted gear and end-play clearances. This owes primarily to the fact that there are no access codes or casting numbers. A reverse synchronizer and a slight offset between two shift gates prevented shifting to reverse while moving forward; it used a nine-degree cone angle and would clash if a shift to reverse about 5 mph was attempted. Between the shift lever and the extension, a rubber isolator kept transmission noise and vibration from entering the passenger compartment.
I'll change the rear end oil every 12K now too. It goes on about what will happen if the level is low but nothing else. The four-pocket, dual-damper spring clutch disc had non-asbestos friction material and was about 11 inches in diameter. Applications Important: These are believed to be the applications but some of these vehicles may have variants, e. Has anyone used this transmission behind their a body? That is — Mobil 1 Synthetic Extreme Performance 15,000 Mile 5w30 Motor Oil. Other lubs specifically for Manual Trannies by a reputable company.
Hard shifting can also be caused by clutch maladjustments or damaged clutch components. To repair this problem it would require the transmission to be taken out and disassembled in order to do the repair. We recommend that you purchase the synthetic fluid from the dealer when working on this transmission. The shaft is supported in the front and rear housings by bushings and one linear ball bearing. The same applied to the output shaft bearing retainers — one of two were used for two-wheel drive, bolts were inserted through the outside of the case and threaded into the retainer; for four-wheel drive, bolts were inserted from the inside and threaded into the case. Normal noises include an audible whine at extreme speeds; other noises are usually due to lubricant issues.
The rest of it will be one solid piece. Select this link to see what. It is simply the author's educated opinion based upon research and contact with lubricant manufacturers as well as implementation in his own vehicle that said product will perform as necessary. The oil level plug is located on the right hand side of the transmission. Use of the Mobil 1 product for this purpose constitutes acceptance of this disclaimer. A combination of roller and ball bearings are used to support the transmission shafts in the two housings.
But if the Mopar lube is synchromesh, I don't remember it saying so on the bottle. Here are a few other items that will help you lock it down. Well, you might be surprised to know that the recipe is very close to the average 5w30 motor oil. Jeep bolted the bellhousing to the transmission case; Dodge did not. Whether this was due to Daimler desires or functional considerations is unknown.
I'll check em' all out. To repair this problem: take the boot off the top of the transmission inside the cab by removing the 4 bolt shifter assembly. Whether this was due to Daimler desires or functional considerations is unknown. To improve quality Midwest was one of the first companies to include dyno testing of manual transmission prior to shipping as a final step in the quality control process. It sounds like a success doesn't it? Specifically formulated for maximum protection in syncromesh transmissions, prevents the thinning effects of mechanical shear for stable viscosity, superior film strength and anti-wear performance. What are you guys using instead? The transmission gear case consists of two aluminum housings. Either get the oil from the Dodge dealer, or get Pennzoil Syncromesh.
This cryo treatment will add 30% in component strength. As such, only Mobil 1 Synthetic Extreme Perf 15k Mile 5w30 fits our needs. This is where you fill the transmission too. A special synchronizer, different from the others, was designed to clash if the driver tried to get into reverse at a speed over 5 mph — perhaps by forgetting that it was a five-speed and not a six-speed. If treated with kid gloves, 100,000 miles is a reasonable change interval.
