Ok Guy's I posted in the general area about this and got no response so i will try it here. I have a 96 Sentra that has 180k on it and i am going through the car to make it fit for comuting again. I was wondering how the tranys are and how long theyb are good for? I would like to service it if thats ok but I don't want to disturb it and have things start to go wrong.(Benn here before). The fluid is not burnt but does l;ook a bit worn. Should I or shouldn't I service it?? I tis the od type trany. Also is it better to drive the car in od or only use the Od for the highway or over 50??

Well I am at 190k and the fluid smells ok? I just don't want to get into any trouble doing the maintenance? I have changed fluid on high mile G.M. Vehicles and had the trany die for no apparent reason?? Is there any other maintenance besides the filter and fluid? Are there bands to adjust?? I just rebuilt my trany on my truck and it was an experience to say the least! In fact I am quite confidant that this trany can't be any tougher?? Well I hope? It will more than likely require all sorts of tools that are special though???

I don't necessarily want to build it but if I have to I will. Are they any good??? What kind of miles are they good for before having to rebuild them?? What can i do besides changing the fluid? Is there a filter? How about band adjustments? I have NO clue with these foreign trany's??

I am on my 2nd Sentra, (1st a 93 XE, now 99 GXE), and aside fromthe crank seal going out, I find the Sentra's engine and tranny damn near unkillable. And I 've tried. I just change the fluid and add a bit of Lucas. No probs.

I got synthetic Mobil 1 fluid from a place called Salvo, if I recall. I beat on my car, so I spend the extra pennies where needed, LOL.

Ya Mobil One or any Synthetic is good but I worry about doing that on a high mile car! Synthetic is like a cleaning agent and will strip all the gunk outof it . This can be very bad for a high mile trans......I think I will try the reguler fluid with some Lucas and be done with it. You didn't mention if there is a filter???

Well, I am almost up to 200k on the original tranny, so synthetic must be at least OK, and I suppose the filter is good for 200k, LOL. I would imagine it has a filter, but you have to unbolt the pan and pop it out. One thing I wasn't willing to do in a townhome parking lot. I was told by a mechanic not to use the hi pressure fluid exchange flushes on high mileage cars. He didn't elaborate on how high high-mileage is. What I do is take some regular trans fluid, drain the old, pour in some new. Idle it, go thru the shift points, and drive it a bit to get all the fluid moving thru the torque converter. Then let it cool a bit and drain and refill. This hopefully gets most of the old crap out. I have had no problems, and I do everything from jackrabbit starts when needed (city traffic) to shifting into nuetral going down hills and throwing it back up into drive on the upslope. Don't use me as an example, but I kinda swing from one extreme from another, and from all the automatic cars I've owned (Civics, Protege, (3)Escorts,280ZX) the Sentra has the most durable so far.

Were you running the synthetic from day one? I'm just not sure if I want to put synthetic in now if it always had Dex from the get go......

Maybe what the mechanic was trying to explain is that you should never flush the tranny with the tranny cooler lines still connected to the tranny. There's a special kit available for flushing the cooler; both lines to the tranny need to be disconnected during the flush. If you don't do this, all the dirt in the cooler will find it's way into the tranny valve body leading to eventual failure.

Really so all the crap gets hung up in the cooler? Hmm maybe I should pull it and flush it? I think not! I'm almost nervous doing anything to a trany with the kind of mileage that mine has Lol!! I think I will drain it and change the filter and add a bottle of Lucas and see what happens. Crossing my fingers.......
