NV3550 Venting Oil?

I recently swapped my AX15 out for a remanned NV3550. Been driving it for a couple of days now and kept smelling a little bit oil burning and chalked it up to be oil that had ended up on the exterior of something burning off during the swap. I came to that conclusion because I could see any new oil spots anywhere. Then today I was driving and suddenly had smoke coming through my floor pan. I am not familiar with NV3550's but the research I had done I was able to locate what I believe to be the vent. There aren't any blown gaskets and fluid appears to be coming out of nowhere. The highest wet spot is where the vent is. If I had overfilled it with trans oil is it possible the pressure inside could have forced some fluid out the vent?

Where did you get the NV 3550 from?


Why did you swap out AX-15?
I'd like to swap one into my '06.

Overfilling is easy to check and correct. Pull the fill plug, let excess run out, reinstall fill plug when no more runs out. Level ground, btw.

Do you have the vent tube in place and running up to the left radiator support.

Also, what fluid did you use, synchromesh compatible ??

2jhanna I did use synchromesh compatible and thank you for the advice. Now time to find a 17 mm hex.
dbb1 The swap was because my ax15 was out of a 92 Dakota from a scrap yard. It is the one from my auto to man conversion. At the time I didn't have the money for a new trans then a couple of weeks ago a bearing or two blew up and the gears ate it all up.
