Who has successfully overhauled an automatic transmission? I have never rebuilt a transmission in my life and would like to know what I am getting into before I even attempt.

The 4th Gen stickies cover only a 5-speed tranny overhaul. Is an automatic tranny overhaul that much more involved?

 

This might help http://www.motorvate.ca/mvp.php

 

Thanks nexgenmax. Motorvate link to the 5-speed tranny rebuild is what the stickies include. I really am hoping someone has something for an automatic tranny as well. I appreciate your response. -Slopster

 

i wouldnt attempt it, even a little mixup can cause big problems. buy a used one if money is an issue

 

While I think it's an entirely doable job for DIY, it would take a good sized clean workspace, the purcase of some special tools, plenty of time, and some serious patience to overhaul one.

In the used transmission market, I think it's far easier to find a reasonably good used auto tranny than a manual tranny. I think you'd save a lot of money and fairly low risk of problems going this route.

Thanks Dave. I'll probably buy a used low mileage tranny but keep my current tranny for a long, slow, patient rebuild. I just want to know how to do it 100% right and I think I can do it over a "much longer than a transmission shop" time period.

Know of any resources Dave? I have the FSM CD for my '97 I30t (it's actually for a '98 Maxima). Pretty good information in there. -Slopster

 

I've not yet gotten into automatics. Maybe when the E4OD in the truck dies but until then...

I suggest you find a good book on rebuilding automatics, since the FSM typically doesn't show the full details on how to handle certain tasks, or what tools and techniques to use when you don't have the Nissan special tools. Also see if the ATSC had a rebuild guide for this tranny, although they may not.

basically its not worth it... u need special tools and it just a wast of time with an auto...

 

An automatic transmission is easily the most complex thing in a car mechanically speaking. I wouldn't bother...
