Transmission leak 200

I've been working on a possible oil leak. I have ordered a new flame trap kit from ipd but will take a week to get to me so I cleaned the old one as best as I could and had to replace the vacuum hose from the intake. That is unfortunately a gas line hose for now. The oil leak has cut down by about 50%. I took the car for a drive to see how it was operating and it started to shift funny. When I tried to back the car in my yard up a slight grade, it would hardly move like the transmission is slipping. Could my leak be from the transmission and what would cause that?

good idea, how do you clean that brass fitting?

The brass fitting Charley advises cleaning is a "calibrated orifice" made to meter the vacuum at idle. It is almost assuredly clogged if the hose you pulled off was, and being clogged, it is largely responsible for the high pressure in the crankcase blowing the oil out of the seals.

A 3/32" drill is usually needed to bust through the hardened deposits without shaving any metal. After that, a pipe cleaner is all you need at each oil change interval.

Ok, I used a 3/32 bit and cleaned it out. It was hard to tell if there was any resistance. I started my 92 Volvo up and let it idle for 15-20 minutes so I could check the transmission fluid. The oil was fine prior to starting. I looked under the car before I checked the fluid level and it was dripping a drop every couple of minutes. I thought I had it but when I checked the trans fluid, it did not even register. I guess that is why there was no leak... nothing to leak. I'm off to the parts store to get fluid. Let you know how I make out.

Best not to work on anything until you know what to work on. How do you know there is an oil leak? From where does the oil appear? How do you know it reduced by 50%. Are you just looking at spots on the ground. What part of the engine or tanny is immediately above the spot? Smelled the leaked fluid. Have you checked Tranny fluid level? I guess the point I am making is that you should perform some very basic observations before assuming anything.

Transmission leak 200

Last week I brought my car home after letting it sit almost 3 months. It was leaking a dark oil like fluid profusely from underneather by the Y in the exhaust pipe. Not on the Y but in that location under the car. It was coming out in a fairly high rate. I was told it was propbably the rear main seal. I am the only Volvo owner in about 100 miles it appears. No resourse around me or junk yards with old Volvos at my disposal so I posted my question on Brickboard last week. I was told to look higher up in the engine for a possible leak and perhaps it was the flame trap. I finally found the flame trap and pulled it. It was dirty but not really pluged. I ordered a new one from ipd but it wont be here until next week so I cleaned this one as best I could in the meantime. I had to replace the vacuum hose from the intake as it appeared pluged and snapped in half on me when I removed it. Again this will have to be ordered so I purchased the same size hose in a brake line. It fits but the rubber is not as hard.. I put it all back together and it appears that the leak has slowed down considerably. I took it for another ride after letting it warm up for quite a while as I had to jump start it. It started to shift funny. Elongated shifting and downshifting. It is an automatic. When I got it home I backed into the yard. There is a slight upgrade and the car hesitated and did not want to backup. It finally did but not like it should. The leak is still oily in color. It doesn't look like transmission fluid but this is a new symptom. I'm not a mechanic nor do I have the benefit of other Volvo owners in my area for help.

If the tube between the flame trap and intake manifold was plugged, there is a good chance that the brass fitting in the manifold is plugged too. You should check that, and clean if need be.

Common leak points of the transmission are the output shaft(if leaking there also replace the bushing)also check where the trans cooling lines are bracketed to the side of the bell-housing,vibration will cause the bracket to wear through the metal lines.

Check the kickdown cable.It may be binding somewhere.

What I mean by shifting funny is when the car is going down the road, not while I'm trying to shift in Drive, reverse, or park. It's dark now, I'll check the fluids tomorrow.

In addition to Fluid Level Checks (hot and cold) also examine the shifter linkage under the car. Sometimes the range of motion can be not so precise and cause the shifter selections to be between each other (typically Reverse and Neutral).

Clean up some of the oil in the engine compartment with a white cloth or white paper towel. Compare the colour to the trans and engine dipsticks wiped on the same cloth/towel. The two should be radically different. ATF should be red.

if your transmission is the source of the leak your fluid level may now be so low the transmission will not operate properly for lack of fluid pressure. if left untreated you will ruin your transmission. check the fluid on level ground with the engine warmed and idling.

We are here to help one another with our Volvo machines.
Transmission fluid is more rose colored, motor oil will
be dark brown/black.
When you check your transmission fluid the car has to be
running and the dip stick has two level ranges one is for
when the car is at a lower temperature and the other side
is for when the car has been running for a while and is
hotter.
I also have a small tranny leak, I live with it for now,
but will fix it soon on my 83 DL (automatic). When my tranny fluid is low the
car has trouble taking off when shifted into gear and this
seems to be when is happening with yours. Don't let it run
low on tranny fluid or your will kill your transmission and
thus maybe the car. Check your owners manual for the correct
type of transmission fluid to use on your model and always
use what they say to use....they know what fluids were best
for the car.

Good luck and do let us know the results...it helps others too.

Excellent advice, not seen often enough here. The switch was made in the 84 model year, from type F to Dexron in the automatics. So your 83 and earlier cars used Type F. The 91 in the subject thread will use Dexron.

Both are red coming out of the bottle, but can turn pretty brown after being in a car for 100K or so. I like that advice given to check the color with a white towel and compare to the dipstick. I never would have thought of that.

I find it difficult to find "Type F" tranny fluid.
If you do use "Type F", it may be wise to stock up a few bottles.

The P/O of my 83 DL hand wrote in the fluid type..."Ford Type"

Probably because s/he could not find the "Type F".

If you ask the clerk at the desk for the correct fluid type...they will
sell you whatever they want... it is not their transmission that
is going to go out....is it? Unless your married to them.

That's just what I did. I pulled what Walmart had left off their shelves, and later got a dozen quarts at an Advance Auto when visiting another town. I was figuring, either that, or invest in Red Line stock. I still have two 83's, and a '79, two having automatics.

It is known as "Ford" type, I'm guesing because that's where it used to be found. Supposedly Type G is its successor, and then I see "Mercon", but my knowledge of oil can be exhausted in less than a minute. Bob is the oil guy, or most anyone, but not Art.
