This is a quick maintenance guide for the 1988-1996 Ford F-150, and 1988-98 F-250, and F-350 (not including new style 1997-98 F-250) pickup trucks, which is taken directly from Haynes manual 36058.
Most of these recommended routine maintenance tasks you can do yourself at home for practically no money, as long as you have a few simple tools and the time to invest. If you need more guidance, or even step by step instructions and a video demonstration, get the online manual, or our traditional printed manual.

Note: This is a dry-fill specification so the amount for a routine fluid change will be substantially less. Determine the amount of fluid to add by measuring the amount drained, initially add 1/3 of that amount. Then, with the engine running, add 1/2-pint at a time (shifting through each gear position between additions) until the level is correct. It is important to not overfill the transmission. | |

Maintenance Schedule
The following intervals are based on the assumption that you will be doing the service work yourself, as opposed to paying to have the work done. These are our recommended minimum maintenance intervals for vehicles that are driven daily, and in many cases are shorter than the factory’s recommendations. Because frequent maintenance enhances the efficiency, performance and resale value of your Jeep, we encourage you to follow our schedule. If you drive in dusty areas, tow a trailer, idle or drive at low speeds for extended periods, or drive for short periods (less than four miles at a time) in below freezing temperatures, even smaller intervals are recommended.
When the vehicle is new, follow the maintenance schedule to the letter, record it in your owner’s manual and keep all receipts to protect the warranty and resale value. In many cases the initial maintenance check is done by the dealer at no cost (check with the service department when you buy the truck for more information).
