RE4R01A transmission Survey

Hi:

It seems that RE4R01A transmission is pretty short.

Tell us how long your trans lasted till replacement/rebuilt

Mine:1993 J30, 120000km (75000kmiles).****s kinda hard from 1st to 2nd. The problem is showhow cured by BG trans service.

Most transmissions last at least thru warranty 6 years and 70k unless abused by owners - by not maintaining clean non acidic ATF.

Anything beyond 100k or 8 years is a blessing depending on local temperature and shifts per mile.

The early year units were redesigned to aid longevity in 1994.

15 years is a record for most Nissans even with 75k.

I'm at 168K with what I believe is the original.

Tech , I know you dont work for Infiniti but is it true you have to know the previous owners name before you get a service record ??Or was I dealing with a snobbish employee.

I pulled up in my "Well Broken in" J amongst a plethera of Beautiful new M's and G's.

I felt like the red headed step child walking in there ..

lol

I was able to get the service records on mine before I bought it over the phone. I think I just gave the VIN. In any case I gave them the info they needed and the local infiniti dealership faxed the records to me. I definitely did not know the names of the previous owners.

Mine is still the original. If the transmission is taken care fo from the beginning, they can last a very long time!

-- I know the feeling, I went once, before I discovered Nico, for a splashguard because I couldn't find it anywhere, needless to say I wont go again. Sad that there's no love for the older models, IMhO, the styles were more understated and refined, and the craftsmanship was better.

-- My transmission has been rebuilt (100k ish) and it's working wonderfully (182k).

Ditto on the Craftsmanship !!Even the all knowing Q45Tech said the new stuff doesn't hold a candle to the old.

His words were.Put a new one on the lift and compare it to the old .You will run away.

Classic line I must say.Although not exactly what he said .. that was the jest of the statement.

I have the original transmission, serviced at 180K(only time I have record of) , now has 208k..... no issues besides the controller losing communication in heavy rain...after I had it serviced. Ran perfect before.

Post by **yodawill2000** » Fri Dec 28, 2007 5:22 am

read somewhere here theres a wiring harness on the transmission that should have a cover to keep out the elements.Might jack it up and see if the covers missing.

Post by **brandonjustice93J30** » Fri Dec 28, 2007 8:41 am

Yeah, Ive heard that's a possibility. And it never does it when I have time to take it to the shop that did the transmission flush or take it to the dealer.

Been busy the last 3 months remodelling a house so I could move into it and then it got snowy and such on me with no garage so I havent been able to get underneath it. I'll check it out once it's halfway warm and I'm not laying in snow.

Post by **yodawill2000** » Fri Dec 28, 2007 9:19 am

Snow ??Whats Snow ??

jus jokin'. No garage here either .Know the feeling well.

i have a rather urgent question......last month i replaced my transmission with a used one due to a planetary assembly failure on the old.Mr. Transmission put in the new used on which had 119k kilometers on it.on xmas eve it broke again. lost reverse and only have forward gears.all the fluid leaked out.took it back and mr transmission says the line busted a leak.here's the question.....is the line a rubber hose or steel hose?also any idea.cause if it was steel there probably was a way of telling if the line was gonna break.if it was rubber then i'm SOL.also no transmission cooler installed.someone please help.

Post by **coolyun_98** » Mon Dec 31, 2007 4:16 pm

If you really want to keep your transmission out of trouble for a long time. Go to http://www.nissanparts.org/ . They sell brand new transmission for about $3k.

Post by **Elisha** » Tue Jan 01, 2008 3:32 am

that still does not answer the question......i need to know if the transmission fluid lines are steel or rubber.

Post by **yodawill2000** » Tue Jan 01, 2008 5:01 am

The lines going to the cooler ??

Post by **Elisha** » Tue Jan 01, 2008 5:45 am

no cooler installed. the shop says the lines carrying the transmission fluid busted.i'm not sure what he is talking about but he says it is rubber lines and i can't see how it would be rubber lines.apparently when i swapped transmission he flushed the lines so that no metal particles remained from the old transmission.so if it were rubber lines i don't see why it was not changed.or if it were steel lines then i'm sure visibly it would have shown old age.either way i'm not impressed that i have to spend money again getting a new transmission or rebuilding this one.

if I wanted to stick with a J, before I'd spend $3000 on one part plus labor....I'd find another J with half the milage and newer ....at least in my situation having a 93 with 208k

And doesnt the J have a transmission cooler integrated into the radiator area or is that an oil cooler from the factory....I thought there was something integrated into that area?

Post by **Elisha** » Tue Jan 01, 2008 10:12 am

not that i know off. i know mine does not have a transmission cooler which makes me doubt there is actually a hose carrying the fluid anywhere. i think mr transmission is trying to pull a fast one on me and not admit that their installation of it was faulty the 1st time.

Post by **edgartheace** » Mon Jan 28, 2008 9:42 am

The transmission oil cooler is in the Radiator. The lines coming off of the transmission are steel until you get to the crossmember below the alternator. then they become rubber hoses, so that they can flex without breaking.

Post by **Q45tech** » Thu Jan 31, 2008 12:13 pm

ATF [planetary] starvation caused by a plugged [restrictive] in rad heat exchanger [common] or a rubber hose leak is #1 cause of failure.

Not just Nissan but every vehicle! When I had a $5,000 Mercedes transmission rebuilt the North American expert outlined theses failure modes also, said more MB fail on a long trip when ATF leaks out from not replacing hoses when tanny is replaced.

Budget swaps and rebuilds rarely replace everything and the thing you skip will cause the next problem.

You should copy and paste your question to the 240sx forum. Someone there will be able to help you.

I know this was from 2007 but:

You don't have to know the previous owner(s) at all. Just get a Carfax on the car (Will help in other ways too) then call up the dealer(s) the car was sold/serviced at, Talk nice to them and they will fax you the service history.

I am thinking it may be the thottle postion sensor or ATF temprature sensor, But check with the 240SX guys.

I have 195,300 miles on the original transmission in my 94 J30T and have never had a problem with it yet. I think the only fluid exchange and pan cleaning it ever had was one I did about 5000 miles ago, at least according to the maintenance records the previous owner gave me.

Post by **yodawill2000** » Sun Oct 18, 2009 11:38 am

I'm at 183K and I did a fluid exchange/filter at 170K.

I think alot has to do with how much WOT you do from a stop.And of course shift count.IE all city wont last as long as all highway.

A cooler helps with longevity as we all know.Hi Temp ATF fluid is not a good thing.
