Is there a bolt that goes the opposite direction in a Nissan Sentra transmission filter and if not why would one take 15 minutes to come out and won't tighten?

Answer 1

A bolts failure to tighten could be caused by either the threads being stripped on the bolt, which would be obvious, or the threads in the bolt hole being stripped which would be hard to check. If the bolt is threaded to turn in the opposite direction (left hand threads) that would also be obvious. You could try chasing the threads in the bolt hole then see if the bolt would tighten, or try a new bolt of the same size. This could also be dependent on the material that was drilled and threaded for the bolt. I own a Nissan, but have not had an opportunity to work on the transmission. My answer is based on generic knowledge I have of fasteners. Hope this helps.

Answerone of the bolts in the filter has a nut on it. If you get the bolt out then the nut will be loose in the transmission unless you get it out. I got the bolt out and the nut but I can't get the nut back in place to replace the bolt. Not enough room to put the nut where it goes!~!!! Any help would be great. I might just leave it out...... AnswerYes, there is a nut and washer on the bolt. It goes into what is called the control valvue assembly. It is really a bad design IMO, but is done simply because this filter is rarely if ever in need of service. In order to repair it correctly, you must remove the "Control Valve Assembly". At this point you can replace the nut and washer back onto the bolt that you removed when replacing the filter. Very few parts houses tell you unless you ask that this is necessary when replacing the filter. In most cases simply spray carb cleaner on the filter while it is still in place and allow to drip dry with some bloding.

Just to add to the last entry - LEAVE THE FILTER IN PLACE - I made the same mistake many others have, and tried replacing the filter. Anyway, if you're at the point of no return, be very careful taking out the valve body, as the small stainless check-balls will fall out, which also happened to me. Luckily, I scavenged them from a parts car. A friendly Nissan parts guy gave me a copy of the valve body layout and where each of the various length bolts and check balls go. A nightmare, but I would advise against leaving the lose nut in the transaxle.

Sounds like you damaged the threads in the aluminum case side... Not on the bolt itself. Find yourself a helicoil kit to repair it and be more careful next time. Thread it by HAND ONLY at first, then use a wrench or socket to snug it (they're only meant to be moderately snug). Helicoil kits can be costly in certain sizes, but if you leave that bolt out your transmission can easily lose the filter (and all pressure with it) and destroy the internal clutches in a short amount of time.

Nissan transmissions are COSTLY to repair or replace. So I suggest you take your time and do it right.
