Question about 1987 GMC Jimmy

Open Question

I have a bad leak coming from the 700r4 transmission to transfer case adapter on the transfer case side. Part stores do not have a seal for this; only the input shaft seal. What is the best way to fix this?

SOURCE: Loosing oil on the output

if your breather is fine, then most output shaft seal leaks can be attributed to a worn bushing in the tail housing. I'd grasp the drive shaft and using an up and down motion, see if there is excessive play. If that's the case, you'll need a new bushing. hope this helps.

SOURCE: Loosing oil on the output

90 percent of the time stop leak does not work. Usually the seal between the transmission and transfercase goes out and forces all the fluid into the transfercase and leaks out the rear seal. Or the tranfercase or transmission breather could be plugged.

SOURCE: oil seal leaking on 1999 gmc half ton 4w/d on front of transfere case do i need special tools or can I drop drive line and replace seal

billbohman: Unless GMC has had some change I am not aware of and that has not been published in service manuals for the repair of these units, the procedures are the same as any seal replacement and require no special tool. There are some universal seal installation tools which I would venture the majority of techs don't have because they substitute other tools in their place most of the time. Most techs will have a special tool designed from removing seals. However, the seal can be removed without it.
Just use a little common sense when removing a seal. Don't damage the casing.
Good Luck.

faulty seals are the common culprits for this. You may want to take the axle out to have it replaced and check the extent of the damage.

Bellhousing leak


did you just have the fluid replaced in the transfer case?? if the answer is no, the you may have a leak from the series of seals that are internal. you will have to have the transfer case removed and have the CVT seal replaced and other seals inside of the transfer case. lengthy repair and costly also. the transfer case has to be removed to replace the CVT side seal and while you are in there replace seals inside of the transfer case also. that what its sounds like to me. transfer case seal leak or the inside CVT seal leak. however if its leaking right from the bellhousing, it also could be the torque converter seal. this is when proper diagnosis comes to play. if its d converter seal, than the trans has to come out. have this one checked by someone that knows what they are doing. could be transfer case seal leak and it could be converter leak.

The transmission fluid and filter were changed out now truck just whines and wont go into gear


There should be a dip stick near the rear of the engine compartment with a red handle on it for the transmission. You want to check the trans fluid with engine idling and the trasmission in park. If it's full of fluid and the vehicle won't move you are most likely looking at rebuilding the trans. To change the fluid you have to drop the pan off the tranmission and the filter is inside. The filter just pull out, the new filter will come with a new seal that presses into the the pump housing. DO NOT attempt to change that seal, leave the old one in place, unless it is damaged. Unless you you have the proper tools to replace that seal you will most likely damage the transmission housing trying to remove the old one. Also, if the transmission is low on fluid, where did it go? Is it leaking on the ground? You may want to check the transfer case oil if it's way overfull the seal between the transmission and transfer case is bad and the trany fluid is leaking into the transfer case. You may want to change the transfer case oil too, they both take Dexron III fluid. Good luck!

Transmission fluid leaking back, 1988 Ford Bronco


your output seal on the tranny or input seal on your transfer case is bad. you have to pull your transfer case to tell. this is a pretty straight forward job. block wheels. put transfer case in neutral. drop front and rear drive lines.diconnect transfer case shift linkage. there is a short commponent connecting the trans to the transfer case. the bolt on either end face each other. remove the bolts to the transmission. the transfer case is heavier than it looks, i suggest getting help. pull back on the transfer case until it will drop down. it will pull out a bit because of the trans output shaft. replace what will probibly turn out to be the tranny output shaft seal and reassemble in reverse order.

Everything was rebuilt on the transmission. However, then driving over 50mph the oil leaks. What can possibly be wrong.


If oil is leaking from the transmission then one of the seals was installed improperly take it back to the person who rebuilt it and ask them to take a look at it for you and repair it if it's warrentied.

Where can I find a diagram on how to replace a seal between the transmision and transfer case on my 2000 GMC Z71? It's leaking trans fluid.


ther are no diagrams. It's not to bad to do. You need to remove the speed sensor(there are 3 of then) Disconnect the encoder motor, the drive shafts, the transmission support and it's 6 15mm nuts and pull the t-case back and twist clockwise and it comes out. You have to support the transmission on a jack to lift it for more clearence

Transmission fluid leak


Get underneath and dry off as much as possible all of the fluid you see. If it is a bad leak, it will drip when the vehicle is off. Place a piece of cardboard down under the vehicle and you will be able to find the area where it is leaking. If it is not too bad, you can pick up and additive from an auto parts store and add it to your tranny fluid. This normally helps to "condition" the seal that is in question...more or less helps the seal to swell for a period of time. Try this first and see where it is coming from. Then, come back and post where you found the leak coming from. Usually it is the tailshaft seal located where the drive shaft connects to the yoke which in turn is "butted" up to the tailshaft housing of the transmission....or the transfer case.

Post back what you find and we'll tell you how to fix what is wrong.

Our 2001 Dodge Caravan seems to be leaking oil around drive shaft


Yes it's a bad seal and most likely the side bearing to the trans axle is bad too. Once the bearing has play, it vibrates and causes the oil to leak though the seal. Note: if one side went bad the other side is soon to follow since they have the same amount of miles on them. Might as well change both side. Good luck and hope this helps. Keep an eye on the transmission fluid level, don't want to burn out the transmission.

Leaking transfer case..


First of all yes it will damage the transfer case with no oil in it or even low oil. if it is just a seal then it is easy to replace, but if it means splitting the transfer case this is not a job for the diy, unless you have experience with transmissions or transfer cases. It should not be too expensive to have the work done by a profesional. Which also give you a warranty.
