1998 12V Auto Valve Body O Ring Failure

RodeoDodge · 02-13-2011, 10:43 PM

The auto in my '98 12V auto won't shift into OD, the rest of the gears shift as normal but the OD will not engage. My mechanic says that the O ring is blown in the valve body and that I have to do a full rebuild on the trans. This is the first auto that I have ever owned, only believe in manuals, but the truck was cheap! Got all the parts to swap in a NV4500 but if it's cheaper or easier to just install a valve body, then I'll have a fresh NV4500 for sale! Lol can anybody give me any insight?

It is time for you to find a mechanic who knows what he is talking about.

This would be a good start

Do a search.

Read the tech articles 'stickied' to the top of this forum.

Learn how the system works.

Fix it yourself and save a bunch of cash.

Your 1998 uses a 47RE trans, but the 1994/1995 47RH transmission's OD and TCC operation are very very similar.

No OD could be a lot of things, opening the tarans would be my last step.
