The 4500 uses a dual cone synchronizer for first and second gears, similar to the familiar, world class T5 design. Some transmission fluids may provide a more robust viscosity on the bearings and gears but fail to take into account the erosion of the synchronizer. It will fit with most any engine even though modification work is always required. Overuse of 4th and 5th gears will cause fatigue and wear between the splines and the corresponding mating hubs. When it was released, many hailed its strengths, particularly the high overdrive, though some have criticized its low gear as not being low enough for off-road use.
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. Nonetheless, for an 'off the shelf' lubricant, Mobil 1 Synthetic Extreme Performance 15,000 mile 5w30 is where it's at. You are looking at gear spans of 7. The problem may get worse, affecting other gears, later. Worn synchro rings can result in gear clash when going into forward gears though they can stick somewhat in new or recently rebuilt transmissions, leading to hard or noisy shifting, which gets better as the rings wear in. See the longer disclaimer at the end of this page. A standard duty version is used for 5.
Leaks can cause extensive damage if not fixed, and can destroy the clutch. Hard shifting can also be caused by clutch maladjustments or damaged clutch components. This is an old school transmission. They are better but not by leaps and bounds. That suggests to me that friction was higher with it, and its higher drag figures taken in neutral gear, coasting down from 110 mph supported that guess. Items such as Mobil 1 Synthetic, Castrol Syntorq, or Valvoline Synpower will all do the job nicely. Do your homework and investigate your realistic needs for the transmission versus what your ideal brand could be.
The transmission is a top loader design with a cast iron gear case and an aluminum shift cover. In 1995, the transmission was adapted and then released in Dodge trucks Mostly Dodge Ram Vehicles. It sounds like a success doesn't it? Using helical gearing with all speed gears in constant mesh and all speeds synchronized, this transmission will handle 450 ft-lbs of torque, and vehicles with a combined gross weight of 19,000 pounds. New Venture recommends customers avoid large load towing while in 5th gear. The synchro ring arrangement requires a unique synthetic lubricant which can be a hindrance see below but overall the composition of the transmission will save a lot of wear and tear. The inhibitor mechanism is located in the shift cover.
Rated Gross Vehicle Weight: 14,500 Dry Weight: 195 lbs. Use of the Mobil 1 product for this purpose constitutes acceptance of this disclaimer. Performance was as expected; which is to say that it wasn't any different. It also has some issues with the carbon fiber synchronizers wearing out however, all around, this transmission will give you the most bang for the buck over for a Jeep Swap. However, when other people are driving your vehicle, or if you learned how to drive stick on your vehicle, or — whatever — you're going to want to cut that down to a 50,000 mile change interval or so.
The 450 Lb-ft input rating is a continuous and conservative input rating for a long transmission life. Do not lose this tag, the information it contains is essential for correct parts ordering! Supposedly this is a 'lifetime' lubricant. Items such as Mobil 1 Synthetic, Castrol Syntorq, or Valvoline Synpower will all do the job nicely. Manual transmission fluid must have the proper balance of gear lubrication that is compatible with synchronizer functionality. But, if you can get the same quality of protection and performance, for less than half that price, and not have to wait for your dealer to be in stock of the item, then why shouldn't you walk right down to your local auto parts store and fulfill your needs? It had a one-inch, 19-spline input shaft and an interlock mechanism built into the 1-2 synchronizer assembly, to prevent downshifts to first and second gears at higher speeds. If treated with kid gloves, 100,000 miles is a reasonable change interval. The bearings, gears and case are all incredibly durable and resistant to wear.
The transmission can easily withstand higher torque from diesels with aftermarket power kits, but transmission life will be reduced in proportionately. A few have reported that shifting was more difficult, most report improvements in the shifting. Well, you might be surprised to know that the recipe is very close to the average 5w30 motor oil. Tapered roller bearings support the drive gear, mainshaft, and countershaft in the gear case. 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. In 1995 the new model of the Cummins 5. Considering you'll only need 3 to 4 quarts the 3500 only calls for 2 quarts, but by the time you pump it in and spill a little, you'll end up using a little over 2, so buy 3.
There is insufficient detergent agent in the alternative Mobil 1 product to adequately serve in this application. In recent years, enthusiasts have found Amsoil makes a 75W-90 manual transmission fluid that is a cheaper alternative to the above. The transmission is too long to retrofit to many Jeeps. Consequently, heavy duty applications for Cummins Diesel and Chrysler V10 engines feature an elongated input and output shaft which is not present on some of the gasoline engine applications. If a leak shows up at the rear of the extension or adapter housing, it is likely from the housing seals; if it shows up at the front, it could be the front bearing retainer or the retainer seal.

In fact, 10w40 is about the same consistency under thermal stress as 75w90 gear oil. The tranny also allows you to keep your original clutch setup which saves both upfront costs as well as labor. Only highly refined or man-made base oils that meet specific performance standards along with proprietary additives are qualified for use. That is — Mobil 1 Synthetic Extreme Performance 15,000 Mile 5w30 Motor Oil.
