Also available are , ,. To make engagement of the first and second gears easier, the 1-2 synchronizer had a dual-cone design that reduced shift effort by up to 40%. Select the parts you require from the following list and give us a call. Hard shifting can also be caused by clutch maladjustments or damaged clutch components. Guaranteed quality and correct parts supplied.
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. 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. Because we use so many new parts, our rebuild process doesn't require a perfect core to be sent back. Applications Important: These are believed to be the applications but some of these vehicles may have variants, e. Hard shifting, noise, wear, and internal binding are usually caused by lubricant issues — dirty gear oil, low levels, or the wrong lubricant. . We offer a no hassle 12 month warranty, performance guaranteed.
Weight was further reduced with the use of a one-piece, aluminum-casting clutch housing and front case. Throughout the years our advancements in 3500 technologies have brought our transmissions to the forefront of the industry. 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. Finer pitch placed more teeth in mesh at the same time, distributing the loads to reduce noise. A wrecking yard or dealer should have an interchange guide. These Transmissions are not interchangeable and have slight variance between the bolt patterns and gear ratios. We specialize in manual transmissions, automatic transmission and transfer cases.
Midwest transmission has been in the automotive re-manufacturing and rebuilding business for 19 years, and shipping completed units world wide. 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. Jeep used it later with its legendary engine. See the complete line of products that we offer at To speak to a Drive Train Expert or to place and order call toll free!

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. Quieter operation resulted from a change to finer pitch gears for third and fifth speeds.
The hardened bearings that we use are designed to withstand tremendous pressure and increase your transmissions longevity. The outer casing goes through an extensive process of conditioning to give it that factory luster you would expect from this type of elite product. Our factory offers transmissions that are dyno tested before leaving the factory, Ensuring high quality. We can help with improving performance and conversions. We recommend that you purchase the synthetic fluid from the dealer when working on this transmission. The use of regular gear and axle lubricants in this transmission can cause destruction. Its corrosion resistant two piece housing allows structural integrity while keeping its overall weight to a minimum.
Through the years, we have isolated certain weak points in these transmissions that need to be addressed. Leaks can cause extensive damage if not fixed and can destroy the clutch. Normal noises include an audible whine at extreme speeds; other noises are usually due to lubricant issues. For 1997 Dakotas, a high-efficiency clutch hydraulic system provided smoother pedal operation, using higher internal pressure for greater precision, reduced hysteresis the difference in operating force between release and engagement , and started engagement closer to the floor. The force reduction resulted from addition of a second friction load path.
Cryogenic Treat any shaft or gear. We take pride in the way our transmission not only performs but looks. Or to discuss in detail the aspects of your vehicle transmission call the Midwest Transmissions Center the drive train expert. Its internal components were also lighter, resulting in easier shifts and a total 100 lb weight savings. For the 2005 model year, Chrysler stopped using the New Venture Gear 3500, moving to the Getrag 238 six-speed gearbox 3. Jeep bolted the bellhousing to the transmission case; Dodge did not.
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. Three different selectable snap rings were used in the constant-mesh transmission; they adjusted gear and end-play clearances. Between the shift lever and the extension, a rubber isolator kept transmission noise and vibration from entering the passenger compartment. For two-wheel drive, it had a long output shaft and rear case; the four-wheel-drive version had a short output shaft and rear case. Whether this was due to Daimler desires or functional considerations is unknown. I also would like to ad that the guys at the shop were real easy to deal with on the phone.
May have been different in later years. On the Dodge Ram, the shift lever extension had a square bore that snapped over the transmission shift lever when pressed down. One of two rear case housings were used depending on if the vehicle was two- or four-wheel drive. Every unit must be thouroughaly tested to be worthy of the Smart Parts name. In the constant-mesh transmission, all gears were constantly in mesh with each other, but none transmitted torque until a synchronizer was engaged — no need to move gears together to engage.
