1991 nissan sentra was leaking transmission fluid

I can only suspect the transmission is bad.
My daughter's car was, and it cost me thousands of dollars to fix it.
It had to be done by a Nissan dealer, no one else would touch it.
That transmission requires a special transmission fluid.
I'm told this was a big problem for these cars.

IF YOU ARE LOSING THAT MUCH FLUID THEN YOU HAVE A SEVERE LEAK, DO NOT PUT OFF HAVING IT CHECKED BECAUSE RUNNING A AUTOMATIC TRANSMISSION LOW ON FLUID WILL CAUSE SEVERE DAMAGE PRETTY QUICKLY

hesitation could be dirty fuel injectors clogged fuel filter,check transmission fluid could be low, transmission could be slipping on take off if it has been a long while change transmission fluid and filter.

With car running and warmed up,pull transmission dipstick wipe clean reinsert and level should be between marks on stick.If stick is dry you are very low and there must be leak.fill to marks and keep car running and look for leak under car if no leak present then drive car a few miles at a time and check level repeatedly.Somtimes tranmission fluid will only leak under heavy driving conditions.If fluid level continues to go down with no leak transmission could be burning trans fluid up,Which is not good.thus you will have to bring to shop.Good luck...Brian

Well...

U have to get ur car to a LiFTER and unscrew the PLUG on the side of the transmission and u could fill the lubricant in that hole.

Opening that plug at the bottom of the transmission means ur going to drain the old lubricant and have to put a NEW gear oil!

At the age of that Nissan, it really needs a GOOD new slicky fluid! additive to go w/ it is GREAT!


Hope the slips everything up!

It sounds like you have a tranny leak. When fluid is low, you will have difficulty shifting or maintaining the gear while driving. As far as where the leak is coming from, it is hard to say just from the post, it would have to be seen to determine exactly where you are leaking from. One possibility is the seal where the input shaft goes into the transmission case. This would require the removal of the transmission in order to replace the seal.

take it to a good trans shop and have them test drive it, they will do that for free, but based on what u say a fluid change will not help, the trans will need to come out for a rebuild.

you have to remove the bottom pan of trannie,inside you find filter

On your model you most-likely have a clutch cable, therefore no clutch fluid. Follow along the drivers-side under the hood, a lever connected to a cable should be a-top the transmission. This should be periodically sprayed with chain and cable lube. Mine is a 1994 sentra GA16DE 1.6 and it still uses a cable. You should periodically change your gear oil aswell. It is much like an automatic transmission's ATF (trans fluid). On most models a fill hole and a drain hole (both with plugs) can be accessed below your transmission. When completely full, the fluid will be even with or just below the point of which the fill plug is slightly draining from being completely full. Most shops will check this free of charge.

yes fill it at the transmission dipstick good luck
