98 Metro Auto Transmission Problem

[metrogirl]

Help. I've had my 98 Chevy Metro Lsi to the mechanic 3 times for leaking transmission fluid. It seems to be oozing up from the top. It is oozing very slowly. I haven't had to put any fluid in it in awhile. They have pulled off all the hoses, bolts, seals, etc. and cleaned and replaced and tightened, etc. and it is still oozing fluid. Now the transmission seems to be slipping when I step on the gas. (This is a new problem. The leaking has been going on for awhile.) Any ideas? Is the transmission just bad. I was having no problems with the transmission at all in the beginning (well, besides the leaking problem, anyhow.) Any ideas would be appreciated. Thanks.

wipe ALL of the fluid off and clean top of tranny. drive it and then look again to see where is is coming from. either you have a seal leaking or maybe a leak at the speed sensor, also maybe vent or dipstick is leaking. verify it that way. also, it may be slipping because you are not keeping up on fluid. any lights on in the dash?

I have the basic, basic, basic dash. There are no lights just an engine temp gauge and gas gauge and speedometer and a light for the airbags. The seals have all been replaced. The leaking seems to be coming from the top of the transmission. The dipstick is far enough away from the transmission that I don't think it would show where it is if it was the dipstick. The speed sensor I'm not sure about. I'll have to call my mechanic and see if he checked that. Thanks for the tips! It's much appreciated.

Cracked case? I had a Contour do that. I had to wash the area down with carb cleaner to find it. I used some 5 min steel to fix it. The lady I did this for works with me and it worked great. She drove the car for 3 more years and traded it in. Still had no leaks.

Tranny leaks are really hard to pinpoint since the fluid sprays all over as you drive. You could try adding leak detection dye to the tranny fluid and then inspecting with a UV lamp. This will show up much better and you may see things that you may have missed by just looking.

As for the slipping - does it happen in all the gear ranges. If so your fluid level could be too low. The correct way to test the fluid level is to move the shift lever through all the ranges first and then take the measurement. It sould also be done with the engine running. This will make sure all the valve body passages have been primed and filled at the time of the measurement.

You could also simply try a fluid change and add some lubegard red once you are done. If this is due to sticky valves it may help.

Also have the line pressure checked. If the oil pump or the primary regulator is failing the line pressure will be low and the servos and clutch pistons may delay engaging. If you only have the slipping in one gear range (1-2 or 2-3) then that circuit will need further inspection/diagnosis.

Hope this helps.
