ok i just bought a 77 mav for cheap . . im a struggling college student and i figure this would be a good oppurtunity to not only learn a lot about motors. . but. . actually be able to get from point A to B. . . my transmission is leaking. . . (automatic) i found the leak. . . its where this tube connects to this chrome colored thing that sits on my transmission. . . the tube isnt attatched with a clamp. . .and extends way back up into what seems to be mechanical oblivion. . . however its the end i can see thats leaking. . . this metal piece the tubes connected to is about a couple inches long. . . maybe an inch and a half think in diameter at the center. . . and about a half to an inch thinck on both ends? first question. . is this the modulator? if not ?what is it? and how do i get up in there to attatch that tube or do something to get it to quit leaking. . i know little about cars and its packed pretty cramped in there. . . if anybody could shed some light on this subject i would be much appreciative. thanks all
evo; sounds like it. If the modulator is leaking, it is simple to replace it. The car will suck your trans fluid into the intake and burn white smoke if it has a bad diaphram. The only other fluid in a line is on the top of the trans, passenger side, where the fluid lines go to the radiator and back again. Concerning the vacuum line, be sure the rubber hose is good, and that the metal one is not kinked. Hope this helps.
the other end is up above someplace and should be connected to a vacuum port on the engine. if the modulator is leaking, replace it with a new one. most screw into the back of the trans. usually about $15 at auto stores.
thanks you guys. . i think it helps. . the end closest to the mod is leaking. . . do you think its possible it just may need a clamp to hook it on there batter? also. . . it dies at stop lights unless i keep gas pumpin through it. . .and as well. . . it needs gas pumpin through it upon starting the engine er else it dies. . . also. . . i have to start out in first even tho its an automatic. . and work my way up. . .does any of this have to do with the mod valve? i was told it might need a rebuilt carburator. . . would lossening the extremely tightened screws around or below the barrel halp with any of this? i appreciate yalls help and any more would also be much obliged. . .
oh yeah. . also. . . theres no white smoke. . and im pretty sure its just the line on the end of the modulator closest to the trans thats leaking. . . i can see it drip out. . and the rest as much as i can see looks dry. . . as far as maintenance is concerned. . . how do i get the thing out or even get up in there to replace it. . muffler and other cumbersome parts are in the way. . . i can barely touch it with more than two fingers.
evol ink, You need a new rubber hose and modulator. the rubber is molded to fit and the only place the oil can come from is the modulator. PaulS
thank you so much you guys i really appreciate all your advice. . ill get started immediately on hustlin up some cash fpr the parts / / evol_ink
ok you guys. . . the tube came off the mod way easy. . . but i traced the line up to where it hooks on on top. . . its not hooked to the engine at all. . looks like its hooked to the m,etal that seperates the area under the hood from the area in the dash. . . is this right? there are two other hoses hooked right by it. . its the one hooked all the way over to the right. . . im thinkin possibly this makes sense cuz the shifters inside the dash coming out with the gear shift next to the steering wheel. . . just checkin up to make sure im not doin somethin stupid. . . advice is always helpful .. thanks guys. just figured id give ya the update.~~
well. . i got it all off and discovered that really the tube just wasnt in there right so i put it back in. .and in an attempt to see if it wold still leak. . tried to turn the engine over. . it started to. . but gradually degraded into a nasty grinding grumbling noise. . . and then went deadf alltogether. . save a little rrrrrrrrrr . . . a little noise like there was still some kinda juice er somthing. . not sure whats up with it. . . then i thought, maybe the heads on the battery need to be clean. . perhaps battery is on its last leg. . so i attempted to take them off. . the positive end . . broke off. . and now i cant get the wires back in. . alls i know is that before it did this. . trying to turn the engine over made the starter very hot on the positive end hook up. . now im just utterly frustrated and confused. . . cuz i know that before anything else i at least gotta get new batt. connex. . . lifes crazy. . .
