    Front pumps usually have some of the top holes tapped for a slide hammer. The ones I ran into that did not I tapped.

    You did not do what I told you the first time, so go here.

    With your attitude you should not even be working on it. Transmission work take a patient cool head, you have neither.

    Well if you work on $50K cars all day you sure don't need my help. Pull the pan and see what maybe holding the pump from coming out.
    You work on German stuff I assume, over engineered and over priced. I worked on Setra Motor Coaches, what a junk.
  • last week when i was backing out of a parking space i heard a loud clunk and all of a sudden i had no reverse. i put it back in park and tried again and nothing in reverse just the motor reving i pusshed it out of the stall and put it in drive it moved in first but revvs reall high until it gains enough speed to get into third . ive tried to put it in second but it just stays in first and it wont go into overdive either .check the fluid and its still red and doesnt smell burnt and th check engine light is not on .any advise?

    Sorry, sun shell broken, common failure. Transmission needs to come out and apart to replace sun shell. If high time probably time for overhaul.
  • Help! My son's '93 S10 with auto and 4.3liter is loosing major trans fluid and we cannot find where. Just recently lost 4 quarts in just 30 miles. It will do this off and on. You can drive it for days and not loose any, then all of a sudden, the whole bottom of the truck is coated. It does not leak when stopped and cold. Only seems to be once it is really warmed up and driving higher speeds. It is not foaming and is not coming out the filler tube. I removed the cover under the torque converter and it appears mostly dry around the converter and front seal. The top of the trans is dry and I checked the plastic vent hole on top and appears to be clear. It is also dry around the cooling lines. The fluid covers the entire bottom of the truck even coating the engine oil pan, all down the sides of the truck and all back along the exhaust and drive shaft. However, when you stop to look underneath, nothing is pouring out. Is is possible that it is building up so much pressure that it literally shoots out of the pan gasket and seals? If so, what would cause this? Any suggestions are appreciated before I need to take it to a tranny shop.

    put the truck on jack stands at four corners make sure it is secure so you can crawl around start the truck get it up to operating temp and then load it in gear and see where its coming from. if its on the oil pan check the cooler lines on the side of the pan they have a tendinse to rub and leak right thare. but it sound like you have a biger problem than that.

    I've heard in some extreme cases, the vacuum modulator can get bad enough to allow fluid to be drafted up the vacuum hose. But in those cases it was being sucked into the intake manifold. Just the same check out your modulator and see if the vacuum hose shows signs of fluid.

    I would think the leak is forward of the transmission because of the fluid on the oil pan. Good luck. :)

    hi was just wondering if someone could help me out i have a 1988 chevy s10 4 cyl. 151 would like to find out if i could replace the trans with a 93 s10 173 .i know the trans mount is different but dont know a freinds got the 93 and said i could have it
  • stev358stev358 Posts: 3
    hi just wondering if any one could tell me if a 88 s 10 4 cyl. 151 standard trans will inter change with a 93 s10 standard? about all i know is the trans mount is differnt so help please
  • Ok so i have heard that the 2WD 5 speed trans always has a problem with the 2nd gear sincro if you race shift the trans. Both my friend with a 4 cyl 2wd 5 speed and myself with a 4.3 2wd 5 speed have that same problem. Just so everyone knows these transmissions suck for racing.
  • Well after checking everything including flushing and checking the cooling lines, new filter and gasket, etc., it is definitely the front seal area. I got it warmed up to the point where fluid was coming out, put it on blocks and could easily see it was all over the front seal/torque converter area. With the miles on the truck (156K), I am taking it in to have new seals and if bad pump or converter will have that done also. Found local reputable trans mechanic who will do seal job for $275. I will keep you posted on what he finds.
  • its a 93 s10 2.8 with a 5 speed and 1st thru 3rd gears are making a horrible noise like theres metal broke in the pan. i drive this truck 100 miles round trip a day. My question is could this be just low fluid and where the heck is the dipstick for the fluid. And what could be causing the noise of metal grinding thru those gears
