Just Changed Transmisson filter. Now having trouble with Trans. Help Please!

[timberfoot]

G'day All;

I changed to filter on my Automatic Transmission today. It was a straight forward job and I didn't have trouble doing it.
I found a very easy way to remove the filter's seal from where the filter plugs in. I used a pair of Cir clip Pliers with jaws that expand when the handles are squeezed together. I put the jaws inside of the ring and squeeze the handles. I then just pulled the the seal out easy as can be.

When I put the new filter in, the new seal slid down the tube on the filter because the friction between the ring and the inside or the transmission was greater than the friction between the ring and the filter. So I put a little trans fluid on the outside the ring of and slid it back to the top of the tube on the filter and reinserted the filter with the seal on it into the transmission. I pushed the filter all the way into the housing. I assume the seal is in place and everything is ok.

I topped up the trans with Dex 111. According to the dip stick the trans is full.

Now to my Problem:

When I first tried to move it off the ramps, the car wouldn't move at all. It was like it was in neutral. I tried to move it several times but it just reved with no forward motion at all. The dip stick seemed to indicate that there was enough fluid, but I added some any way. After that the car moved better. I took it off the ramps and took it for a small, Slow test drive. It was reving way to hard for the speed. I added more fluid, Now it works better. The dip stick indicates that the trans is slightly over full...

Now when I take of after the car has been sitting a while, the engine revs, but the car doesn't accelerate very much. It does move off, but definatley revs harder than is should to move forward. Of course the car lacks power also. However, once the car has warmed a little it seems to behave normally or close to normally.

Does any one have any ideas about what the problem could be? I would appreicate any help.

Cheers
Matty

That seal shouldnt be able to slide down the filter like youve mentioned. It should just fit over the end of the filter pipe and thats it.It shouldnt be able to slide down it at all. I always soak the new seal first in clean trans fluid,I fit the new seal to the filter first up, and then I push both the new seal and filter together up into the trans until I can feel that it is pushed fully home, and this always takes a fair bit of pressure to push it home, and Ive never had a seal move down or slide down the filter pipe like that, so Id say that the seal is stuffed and that could also be why its now having trouble getting going, its probably sucking air in through that seal which will then make it very hard for the trans to suck up the fluid from the trans pan up through the filter.

Thanks Brett_jjj

Thank you very much for you advice.

I think you may be right. When I pushed the filter in, it went in with easily, I didn't have to push very hard at all.

I'll take the pan off again and see if I can put the filter in better. Otherwise I'll be taking it to the place I bought it from and exchanging it.

G'day all;

I still need some help.

When I took the new transmission filter out of the box, the seal was on the tube on the filter. I assumed that whole thing should be installed at the same time, the tube and the seal. However, as I wrote above, the seal slid down the tube. Should the seal be put in first, then the filter inserted into the seal second? or should they be able to be installed at the same time?

When I took the pan of my transmission the second time, the filter was sitting in the bottom of the pan! Obviously it was not installed properly! So, I tried to put the seal in with out the filter, but I could not get it in? Is there a method for putting the seal in?

Once again, I would be grateful for any advice anyone could give me.

Cheers

The normal method of installing the seal is to use a drift (such as a socket) which is the same size as the seal and hammer it (lightly) into position until fully seated. Also, when checking the fluid level, you need to have the trans fluid warm (around 15 mins driving), park on level ground with the engine running and foot on the brake, move the selector lever from park into each gear (holding it for a few seconds), until you get to reverse, then move the lever back again the same way until you are in Park again. Leave the engine running in Park (with hand brake on) and check the fluid level. If not at the Hot mark top up with more fluid until the correct level is reached.

Exactly, I was about to say the same thing. You need to tap the new seal into the transmission until it seats, then push the filter into it. That will be your problem.

[Brett_jjj]

Just soak the new seal in clean trans fluid first for a minute or two, then push the new seal on the new filter pipe first, and then push both the new filter and new seal into place up in the transmission filter locating hole until the filter is pushed fully home.Then give the filter a light tug back outwards to make sure its in there nice and firm and cant come back out easliy. Ive done it this way hundreds of times over the years now and have never had a problem with a seal or filter not sealing etc.You dont need to fit the seal in the trans first at all.
As I said in my first post,the seal shouldnt be able to slide down the filter pipe at all, it should only be just able to fit over the end of it, so is most probably a faulty one.

I'm pretty sure there are two different kits. Low pan/high pan for want of better description. Just a thought

[Not_An_Abba_Fan]

The seal has a metal casing that is pressed into the hole, not like earlier ones that is just a rubber O ring. No amount of soaking will make it any easier to fit. It is a press fit and has to be tapped into place.

[Brett_jjj]

Yeah,its a metal case on the trans seal,and it has rubber seals bonded to it to do the actual sealing, and dipping it in trans fluid has got nothing to do with making it fit easier,it just starts the swelling of the rubber on the new seal so it will swell slightly which helps seal it up properly once its fitted and in place., the same principal as when you put engine oil on the new oil filter seal before its fitted to the engine to start the rubber seal swelling so it seals properly.Ive never seen a rubber o ring seal used on these transmission filters,not even on the older VN and VP models.Theyve always been the metal/bonded rubber type seals..

[Not_An_Abba_Fan]

I did a shift kit on a VN SV5000 and it had a rubber O ring.

The issue the OP had was the filter fell out because the seal wasn't seated in the trans properly.

[Brett_jjj]

Ive never serviced any VN/VP V8 transmissions, so they probably use a different seal to the V6's,I dont know. All the V6's Ive ever done, have the metal/bonded rubber seal.
Yeah, I already know that this guys filter seal wasnt fitted properly,causing the filter to fall out again, I was first to post up that the seal was probably the guys problem..

[Not_An_Abba_Fan]

And I've never had a seal push into the transmission just by fitting it to the filter, it ALWAYS slides down the filter because the rubber stretches. The seal needs to be pressed into the trans first, then the filter pushed into it.
