95 BLKDOUT Drop Top Posted June 14, 2004 Report Share Posted June 14, 2004 two questions: 1 is the trans fluid cooler and oil cooler one unit in a 95 CS 3100? and 2 if the cooler went bad would that cause the lines to leak and the trans to shift bad and make noise? i was leakin oil and trans fluid but now since i changed my oil last week its just leakin tranny fluid from those lines and the trans is whinin a little and shiftin funny Quote Link to comment Share on other sites More sharing options...
WhiteOut Posted June 14, 2004 Report Share Posted June 14, 2004 If the lines are leaking that go to the cooler it can have a slightly detrimental effect on shift performance since the line pressure is affected, but it won't be that noticable. More than likely the shift performance is being hurt by air in the lines or a low fluid level. I would assume your refering to the lines that exit from the trans near the flexplate area and then go off to the trans cooler. If thats the case they're pretty easy to do yourself, they don't cause a big mess, and most dealerships have them in stock. I believe they cost something like $23 a piece. Do both of them at once, and save yourself the trouble of doing it again. Both of the lines on my car developed leaks this past winter at the joint where the hose goes from being rubber (trans cooler end) to steel (trans end).

WhiteOut Posted June 14, 2004 Report Share Posted June 14, 2004 Wow, I had my tranny replaced last September, and BAM!!! a month later my lines started noticably leaking as well. They must not like to be jostled after they get old. Oh, by they way, routing the lines is a mild PIA. The only other remotely difficult part was getting a tool up to the tranny cooler to remove the sqeeze type hose clamps GM is so fond of. I replaced mine with screw type clamps, you may want to do so as well when you see how much fun the squeeze type are to remove. Quote Link to comment Share on other sites More sharing options...

WhiteOut Posted June 14, 2004 Report Share Posted June 14, 2004 Anthing related to a pair of pliers. I think I ended up using a pair of 10" bent needle nose to get the job done, but I tried channel locks regular pliers and a whole bunch more. That space is damn tight and a tough to get at with a giant set of pliers in hand. Quote Link to comment Share on other sites More sharing options...
patgizz Posted June 14, 2004 Report Share Posted June 14, 2004 definitely do not run it low, these things are picky about that. hopefully going low didnt do any damage. i would add a bottle of lucas transmission additive as well to help lubricate everything well iincase anything got a little hurt from being run low on fluid or getting air in the lines.

95 BLKDOUT Drop Top Posted June 14, 2004 Author Report Share Posted June 14, 2004 hey pat, hows it goin? ok well i just finished replacin the lines, results yet to be seen seein how im baby-sittin today for my aunt till like 8:30 so i wont be goin any where for a while, ima be here watchin rugrats and spunge-bob for a lifetime, but any hoo i concluded theres nothin wrong with the tranny because this mornin when i was goin to start on the lines i started it up drove it around the block and back to the house. it acted the same so when i got back i popped the hood and checked the fluid and it was like only a little drip drop on the dip- stick wich is tellin me the leak had gotten bigger since yesterday (drove it about 160 miles to and from sandusky) i filled it up when i got home and the car hadnt moved since then so it had to have gotten bigger from the trip, but ill see tonight if its ok.

Yeah i use a pair of 6" needle nose vice-grips that almost wouldnt fit in that little space. i hate those clamps that GM just adores, they're even on the new GM's (2004 chevy impala SS 3800 II s/c) i dealt with them changing a lower radiator hose in a 88 G-body cutty Quote Link to comment Share on other sites More sharing options...
93CutlassSupreme Posted June 15, 2004 Report Share Posted June 15, 2004 they're probably easier for hard working uaw workers to slap on than a better clamp design that requires turning a screw or nutdriver Quote Link to comment Share on other sites More sharing options...
