I was going to Grandjunction here in colorado, its a 4 hr drive to get there from denver. well i left at about 4 in the mornin to beat traffic. im starting through the mountins in 5th gear next thing i know my rpm's when flying. i down shifted to 4th and no prob. i tried 5th again rpm's would move the max wouldnt. im not leaking anything, 1st through 4th work fine along with reverse. so i limped my my back home after pulling off, heeeeeeelp any ideas please. i have 130,000 miles on it. friday the 13th struck

 

Ive lost 5th before due to the bolts not being tight enough that hold the tranny to the engine. I would also check your linkage and see if you can shift it into 5th with the car off.

 

ya i can go into 5th with the car off i havent looked at the linkage yet though...thanks for the starting point!!! anymore ideas keep um comeing i got all day tomarrow to work on it thanks James!!

 

Could be the synchros.

 

i appreciate any help anyother ideas, or suggestions. thanx S.S

 

for the synchros. Happened to a 1990 Saab 9000S I used to own. The good thing is that the car is still driveable, the bad thing is you never know when the next gear(s) will go out. Have it looked at ASAP.

 

how much dose it cost to get the synchros repaired if its someting i cant do, thanks Maxgig.

 

Synchros would require opening of the transmission and is very costly (depending on shop but most cost a lot). The cost is mostly labor though, if you are good with tools, have lots of patience and can follow a service manual you should be able to tackle the job, thats the way I learned to service transmission. But if your not comfortable you can shop around for prices. I would make sure that its 100% sure its the synchros though. Its hard to diagnose through the internet.

 

i agree i will start with the basic's first. thanks 4 all the help

 

Have you grinded 5th alot? Id imagine the 5th gear synchro would be last to go, seeing as the 1-2-3-4 synchro are used a lot more. and you dont normally shift fast into 5th gear..well atleast i dont, dont race people doing 130+ mph lol..

Anyways it sound like it could be internally related seeing as you can get it in while the car is off but not on.

Synchros are expensive and require the whole tranny to be dissasembled. If i were you, id get another low mileage unit from the wreckors or off the org. Cheaper initially, but in the long run who knows. whenever you get anything from teh wreckors you have no clue what condition its in unless you tear it apart, and if you gunna do that may as well rebuild the original unit.

 

Try a transmission flush and see how that goes.

 

well before i tear into anything i'm going to try the small stuff first. i havent grinded fifth hardly at all! i can get it into fifth gear when the car is eaither on or off, its just when im driveing and i put it into fifth nothing happens, i can rev the engine, watch my rpm's go up but it acts like its just at idle.

 

well bad news, its not the linkage, but thanks for all the help

 

honestly your better off replacing the tranny with a used one w/ low miles. the cost of having a shop replace the syncros maybe double the cost of a used tranny. plus while your at it, you might as well upgrade the clutch at the same time if you haven't already done so. i would call around to different yards to find one or see if anyone is parting out/selling their car/tranny. if you do end up replacing the tranny, take some pics of the inside of the oil one for the .org to reference from. good luck.

 

ya i def. want to upgrade while im at it. new clutch and light weight flywheel. makes since. i have my Blazer so its not too big of a rush, plus i need to get money together. how much should they go for. ballpark figures if anyone knows?
