John Wood Big Bore Transmission Dipstick Adapter 1994.5-2010
The factory dipstick / oil fill tube on the early Ford HD transmissions (1994.5-2010 model years) are a press in type that depend on a Teflon coating to seal and keep the transmission fluid in. Often times the Teflon coating does not seal entirely and results in a fluid leak. John Wood has made this two piece tube that utilizes Viton o-ring seals that will insure a leak free life of the part. This product also allows for a simple removal that allows you to remove the lower part of the dipstick / oil fill tube from the transmission case while the transmission is in place. Replacing the factory tube requires removing the transmission, the repair tube does not require removing the transmission making the repair only a 20 minute replacement versus a 5 hour repair.

Excellent fit & finish!
The dip stick tube was very easy to install and is built extremely sturdy. Best thing of all is no more fluid drips in the driveway!

Works Great
After one week of use no leaks. Not much info on installing it. Installation is pretty straight forward, just don't even try to completely remove the 19mm bolt. If you do good luck getting it back in. Just loosen it enough to remove the lower tube. Have plenty of socket extensions and a swivel on hand.

Fixed the leak
OEM tube is laughable. This has o-rings and seals properly. Fixed my leak.

Stopped the leaking
This seems to have stopped the relentless leaking from my original transmission dipstick tube, which apparently is not ever meant to be removed and replaced as the friction-fit fails, a gap i created and it starts leaking. I tried some JBWeld around the OEM dipstick tube, but it didnt stop the leaking. This is an expensive part but the only option and thankful for it.

Alright
Bought this to fix my leaky dipstick and this still leaks when it’s cold. After the trans warms up it seems to slow down but spending that kind of money and it’s “construction” it shouldn’t leak at all

Excellent product
Had it installed in about 20 to 30 minutes. Fixed the leak I had on my e99 4r100.
