Fluid type explained
The 2020 Jeep Gladiator comes with two transmission options: a DSI MFT-6 six-speed manual and a ZF 850RE eight-speed automatic. The manual transmission uses Mopar ATF+4, while the automatic uses Mopar ZF 8&9 Speed ATF. Both are synthetic-based fluids designed to provide long-lasting protection and performance.
Service procedure
A drain and fill is the most common service procedure for the 2020 Jeep Gladiator. This involves draining the old fluid from the transmission pan and refilling it with fresh fluid. A full exchange, on the other hand, involves flushing out all of the old fluid and replacing it with new fluid. This is typically only necessary if the transmission has been contaminated or if it is being rebuilt.
Service interval
The recommended service interval for the 2020 Jeep Gladiator is 60,000 miles for the automatic and 30,000 miles for the manual. However, if you frequently tow or drive in severe conditions, you may need to service your transmission more often.
Common transmission problems
Some common transmission problems with the 2020 Jeep Gladiator include slipping, hard shifting, and delayed engagement. If you experience any of these problems, it is important to have your transmission checked by a qualified technician as soon as possible.
