Transmission

Transmission questions seem to be popular now. ( I have a 69 beetle) Here is my problem. My driveway is on a slight incline. When I go to back out of the driveway if I leave the car in in neutral the car smoothly rolls down the drive way. If I put it in reverse and hold the clutch in and try drifting back it only rolls about half as fast. As soon as I put it in neutral you feel the drag go away and it rolls smoothly again. The only gear that I have to baby while shifting is when I shift into second. Running at high RPMS and letting off the clutch does not cause the transmission to pop out of gear in any gear.....that's how I read to check a transmission. A little history. This car sat for about 20 years in a garage until the original owner got old and gave it to a friend who sold it to me. When I first got it I changed out the transmission fluid among other things. Its been two years now and I now have about 500 miles on it since getting it back on the road. (I was deployed for 9 months or it would have a ton more on it.) Is there some kind of cleaner, or some way to flush out the transmission other than to just change the transmission fluid periodically. Any recommendations on types of transmission fluid to use at this age? By the way, I did adjust the clutch and it is set properly. Thanks for any help in advance. Doug

And your problem is what, exactly?

Cold transmissions, turning more gears, take more effort, because of the heavy oil viscosity. Notice any difference in your rate of drift down the driveway in winter?

Just make sure you got the right weight and grade of oil in it, and check the level once or twice a year - more often if you got thick oil dripping off your car.

...................Switch to synthetic gear oil. It flows better when cold. You didn't mention how it rolls down your driveway right after it's been driven for a while. If it's better at that point, then using synthetic gear oil will help free things up when it's still cold. I'm using Amsoil 75W-90 that's rated for for GL-2 through GL-5 applications. GL-5 only stuff like Mobil1 might damage the yellow metal parts in your tranny but there's been some confusion about whether that's really true. You shouldn't have any trouble finding an Amsoil retailer in your yellow pages.

You are measuring CLUTCH drag, and it seems a little draggy, but wont cause any concern. Maybe it just has too much free play and does not disconnect completly.

Just changed the transmission oil. Man was it ugly. I went with the 80w90W Hypoid Gear oil it said it was the equivalent to the GL-5. I used exactly what the book suggested. What it had listed as suggested oils werre.... "API GL-5 SEA 75W90W" OR "80W90W Hypoid gear oil". I got Tims response to late for his warning. Anyone know what HYPOID is? I am starting to lean towards the clutch not disengaging all the way. That makes sense. I was teaching my daughter to drive a stick these last couple weeks . It needs it after that anyway. LOL She just got her permit so if your in VA Beach anytime soon look out for a tan bug. LOL

Hypoid is correct, single grade GL5 however is not. It is corrosive to the yellow metals used in the tranny, this happens over time, so you are ok if you change it in the near future.

Castrol makes a fully synthetic GL4 rated oil, SFX something, works great!

Thanks for the help and advice. As sluggy as it was I will be changing it again soon just for healths sake. Never had a tranny open so I don't know what yellow parts are but I will avoid using the GL-5. Doug
