I'm trying to replace the transmission filler/dipstick tube in my 2002 Buick LeSabre and I cannot seem to find an applicable replacement. I got a GM part number (25669898) from parts.nalleygmc.com. I tried ordering the tube from them, but they told me it wasn't available anymore.

I damaged the tube while trying to remove the spark plug boot, and the tube-to-case seal began leaking transmission fluid a few miles later. I purchased a replacement grommet/seal, but the original didn't look damaged when I took it out, so I'm worried that the tube itself may be slightly kinked.

At this point, I would be happy with any filler tube that is the correct length and makes a good seal into the transmission. I wouldn't mind having to modify the mounting bracket. Problem is, I can't find any tubes that advertise as being compatible with the 4T65-E transmission. It seems like they don't exist. I even tried calling local junkyards. Please help.

Leaking trans oil in Houston,
