Whining sound in my tranny ***MORE FEEDBACK***

MMamdouh · Post by **MMamdouh** » Wed Dec 14, 2005 4:13 pm

right after i replaced all 3 engine mounts on my 1.5 SOHC lanos i noticed a whining sound from the tranny... very noticable at 2nd gear and a little bit on 1st and 3rd... what can cause that?

i see it is almost impossible that i toasted my tranny... OK i drive had but the tranny got 69,000 Kms on it which is some 4,3125 miles so can a tranny bet busted in such short distance?

also does the mounts have something to do with this? i only noticed the sound next morning after the replacment and i know it was not their before... need help guys.

i went to the mechanic to see whats wrong with my tranny and he told me to try an idea which sounded so familiar... replace tranny fluid with PWS fluid

i know that you all suggested that i don't do this but given the setuation i am in i had no other choice... the mechanic said i have to change the tranny oil as i have never did that before (69000 kms of usage) plus the fact that the oil they use on the Egyptian assembled cars is crap, also he said that the trannys he used to buy from the shop that imports used car parts contained PWS fluid in them.

what do i have to lose? if that fixed the tranny then i am happy but if it didn't then i am looking at a tranny replacment anyways

i am only surprized that a tranny can go bad after 69000 kms only... i mean i should have busted some CVs and needed a head job or so before my tranny gets busted... right?

anyways i went with the change and the old oil was kinda dirty as if it had some little dust and theur was 4 or 5 solid (probably metal) grains in the pan... i only missed second and third gears 2 or 3 times throughout the 7 years of use so can that be it?

i tried the car with the PWS oil in the tranny and the sound is indeed much lower but not gone completly... i went for a test and pushed the car to 150 kms/h going 80 kms/h on second 110 kms/h on third 130 kms/h on forth and then 150 kms/h on fifth and it was all fine.

also went for a nice sprint/ braking drive where i do up and down shift through 1st 2nd 3rd 4th gears so many times... kinda like rally driving where you accelerate fast then brake hard and accelerate again and so forth... again every thing was nice and the tranny was very responsive, still the sound exists but not as loud as it used to be.

i am not sure what to do now... should i keep that PWS oil in or get some W80 oil as instructed in the manual or replace the whole damn tranny?? i got a friend in the car and he told me the sound is audiable only if you try to listen to it with no cassette so i can live with the sound but i will have thing like a splinter in my mind telling me "you got a tranny problem" and it won't go away.

what do you suggest guys??

If you have a manual tranny and put power steering fluid oin it you will destroy your tranny. Only auto's use tranny fluid/steering fluid. You need gear oil in a manual tranny to protect the gears. Try some manual tranny conditioning oil like slick 50 for manual trannys. and put fresh gear oil in 80 or 85 w should be good. I'm gonna change mine to royal purple oil

i have a 5 speed manual

and yes this is practically putting my money where my mouth is or to accurate putting my money where the mechanic's mouth is

BTW if i ended up getting a new tranny is it any good to get one of them F20 trannys for my 1.5 SOHC?? i suppose i have the F16 and i don't know if the F20 will fit or provide better acceleration and all so a tip will be very helpfull here.

I think it will work but doubt its worth it. The f16 has a closer ratio (actually i think the final drives are the only difference)...other than that the f20 is just beefed up better and can hold more power...but im guessing it weight more also. I think your better off w/ what you have...maybe change the final drive. The f16 is good up to 190bhp.

ps.. i just looked all this up.. cause i sure as hell didnt remember any of it!

190 BHP?? then i am sticking with the F16 i have... even if i got myself a 2.0 in the distant future i won't be even near 190 HP so no need to put a heavier tranny on the woo.

feedback on my tranny issue:

the tranny whining sound is lower indeed but still noticable and guys that were in the car told me it doesn't sound that bad that you need to replace the tranny... at least not right away.

now the PWS fluid is not working as good as the old oil... i can feel a bit of a "bite" when engaging 2nd and 3rd gears some times and i don't like it... i think this is the price you pay for having the wrong fluid in.

now hwere is my plan... i am going to keep this PWS fluid for a couple of days more and then flush it and put in SAE 80W (as per the users manual)oil in the tranny, i am only keeping the PWS oil as a flush oil as you know i found little solid objects in the old oil so a flush would be helpful.

if you have any other suggestions or comments i am all ears.

couldn't wait till the end of week as one of my friends scared me and said that by the end of the week the tranny will sound like a tin can full of crockery so i went and replaced the PWS oil.

the oils was a bit dirty probably from the resedus of the old oil and it really seems too fluid... i know it is the nature of PWS fluid but i guess this desn't meet the tranny's requirments at all.

i filled the tranny with gearbox oil and now the whining is even less than before... couldn't really test the car as the gas station is just 3 Kms from home but the buffer is promising... more feedback tomorrow.

if you wanna know the summation of this whole PWS fluid deal: i couldn't really tell in 4 days and 175 Kms of testing but so far it sjowed nothing promising to try this again or recommend it to any one.

one thing though... the guy at the gas station told me (after knowing that i had PWS in my tranny) that the only manual trannys that got PWS oil in them are the OPEL trannys and kmowing that our cars are based on the OPEL Astra then he must have been talking about our F16's.

he also said that even though the lanos is based on an Astra still all Lanoses that came out in Egypt got tranny fluid rather than PWS oil... i really don't know if this was true (the bit about PWS in OPEL cars) so if any of you guys ever heared of that... please advice.

Get rid of the ATF out of the gearbox ASAP. It is not necessary to get SAE80 GL4 gear lube. 75W90 GL4 gear lube will do too. In fact, any manual asking for SAE80 or SAE90 GL4 and 75W90 GL4 gear lube can be used interchangeably with one another.

GL4 is important! Make sure it is API GL4 spec'd. Using gear lube that is not GL4 spec'd will mean addtives attacking the yellow metals in the gearbox like brass.

i got no idea what type of fluid i got this time but i am sure it is tranny fluid... the ATF is already out and the new fluid is "heavy" rather than the "too fluid" ATF.

anybody got feedback on ATF in OPEL cars clames??

The ATF in Opel cars is Dexron III.

MMamdouh · Post by **MMamdouh** » Mon Dec 19, 2005 3:19 pm

so it is true that "manual" tranny OPELs uses DEXTRON III as a tranny fluid... having said that then our GM F16 tranny can use DEXTRON III (AKA ATF fluid) as a tranny fluid... right?

I'm a bit confuse here. You asked for Opel ATF and it is Dexron III but only in the automatic transmissions. The manual gearboxes use GL4 rated gear lube. It can be 70W80, 75W90, SAE80 or SAE90.

i am simply asking if any OPEL manual tranny ever used ATF as tranny fluid.

that is a clame one guy at the gas station said and i don't really beleive it so i needed confirmation.
