Overview
The Omix-Ada 18886.83 is an oil filler pipe for the AX5 manual transmission. It fits 1987–2000 Jeep Cherokee (XJ), 1997–2002 Jeep Wrangler (TJ) and 1987–1995 Jeep Wrangler (YJ) vehicles, with trim coverage for each model.
A filler pipe carries transmission fluid into the case, so it plays a role in fluid level checks. Compare the old pipe with this one before fitting, since material, length and seals need to match your installation.

Fluid level and filler care
The filler pipe is the route for adding transmission fluid, and it is also the reference point for checking the level. A pipe that is bent, cracked or loose can leak or allow dirt into the case. Over time the rubber seals and the pipe’s connection points are exposed to heat and road grime, so they can wear and begin to weep fluid around the transmission.
When the pipe is removed, clean the mating surface carefully to keep debris out of the case. Use the correct transmission fluid type for your AX5 and fill to the level given in the service manual. After a test drive, check the area around the pipe for drips and recheck the level once the transmission is warm.
- Inspect the pipe for cracks or bends
- Clean the mating surface before reinstalling
- Recheck the area for drips after a short drive
