Help with reverse issue. My 1978 Westy runs great but this morning I jump into my bus to head out and it would not shift into reverse no matter what I did. It seemed to go into second no matter how I shifted. After several miniutes I gave up an borrowed my wife's car. I have done some research and I am thinking that I need to adjust the housing as it may be too far backward? I tought I would see what you guys thought. The engine only has 3500 as well as the clutch and the tranny. There are no issues with the other gears. Thanks in advance!

check the rear coupler on your shift linkage, sounds like it spinning on the hockey stick when you try to hit reverse, thats why your hitting 2nd, it won't turn the hockeystick far enough to get reverse.

I am looking at my repair manual and trying to figure out the best attack plan. Should I remove the gearshift bolts and stop bracket and look at that area first or do I attack the coupler from underneath the bus. Also when adjusting the couple do you know if I need to remove the square bolt and adjust it or is there another way to adjust it?

Sorry for all the questions and your help is greatly appreciated. Thanks

after i changed my clutch cable, I had same problem after couple of weeks, - cable stretched a bit, and first thing was that reverse gear didn't go in. So try to shut engine and if then goes - it can be clutch cable, so needs adjustment from back wingnut. If gear won't go in even when engine not running - something else is wrong!

Get someone the move the shifter around while you lay under the bus looking up at the coupling. That should tell you pretty quick if the problem is with the coupling or elsewhere.

You can just have someone try to put it into reverse while your under there looking at the coupler & see if it moves with the linkage/shift rod, but don't have the engine running while your under there unless you fully trust the person trying to put it into reverse. L.O.L. There is no adjustment on the coupler, only you shifter base can be adjusted, but if this happened all of a sudden I don't think it your shifter that needs adjusting. What protus said is possible, but you cable if not new might be slowly braeking, so check you book for clutch cable adjusting and make sure you clutch pedal/cable insn't to loose. I myself would check all the things mentioned before ripping anything apart, that way there your not waisting time taking things apart that really don't need to be, just do some inspections by eye, but I would suggest picking up a spair clutch cable, they are always good to have just incase. My old 79 bus decided it wasn't gonna go into reverse one day at work, so I pushed it out of the parking spot & started driving home only to loose the ability to shift into 3rd & fourth, so I drove to my buddies shop in 2nd gear, put it on the lift & found my rear coupler was messed up, it wasn't broke in 2 pieces, it just cracked at the welds that hold the piece to the shift linkage & allowed that piece to spin freely from the part connected to the hockeystic/nose cone. I'm sure it sounds confusing, but It's kinda hard to explain. Here's a pic of the coupler I'm talking about, see the round part at the bottom, that came loose from the big square part, so only that would turn when trying to shift and the big square part wouldn't move, so it may look OK, but could be shot. Hope that helps alittle and keep us updated Wink

I agree 100% with mintonman about the shift coupler. I was unable to find shift into reverse until yesterday, when I finished replacing my coupler. One word of advice if you do replace it, it is STUBBORN! I ended up having to destroy my old one just to remove it.

Man I really appreciate everyone's input and help. Let me tell you what I have done so far. I noticed this issue in my garage where I could not put in in reverse. It fels like the other gears where fine. Today I climber unerneath to take a loon at the couple like was recommended, by the way that photo you include saved me hours of looking. Thank you so much. Anyways while underneath I had my buddy shift into the different gears and the couple looks fine, meaning the round piece that is supposed to stay fixed was fixed and not moving. Maybe the coupler could still be the issue? but it looks to be working correctly. We pushed the bus out in the street and fired it up and gave it a try. It started right up and shifted into 1st with no issue. Off I went, then second was no problem but when I tried to shift it into 3rd, no luck if I finessed it and got it in gear it would be 1st gear and not 3rd. 4th gear was the same problem I could not get it into 4th but if I worked it it would go into a gear but it would be 1st gear. Very strange. So I decided to try adjusting the shifter base in the bus at the base of the stick shift. There a 2 bolts and you can loosen them and move the unit forward or backward. I tried several different placements and could never solve the issue. Still no reverse, no 3rd and no 4th. There is no grinding smoke or strange noises or smells. I still think it may need to be finely adjusted at the shift base unit forward or backward?

Any other thougths or suggestions? Thanks a bunch you guys are all great for helping!

If you read the end of my post with the coupler picture you'll read that my problem was identical. I would just order a coupler & change it, the shifter doens't need that much FINE tuning to be able to hit all gears and the whole coupler should rotate clockwise and counter clockwise as you move the shifter to the right for 3rd & 4th gears or to the left for reverse and if it's not rotating it will only got into 1st & 2nd because the shifter doesn't have to move side to side for these gears, just foward & backwards. Here's pwilsons thread about removing the coupler, you might need this info http://www.thesamba.com/vw/forum/viewtopic.php?t=265311

OK, thanks. I will report back. I am going to remove the coupler and put a new one in and see what happens. I think that should work, like you said. Do you recommend any retailers fr getting the coupler? Also I read the link that you sent me about the coupler which is very helpful. Do you have any tipps for making the job easier? or any must know details in doing this job?

Thanks

I got mine from German Supply.

shift coupler

I was very pleased.
Like I said, my old one was not easy to remove. I ended up using a dremel to cut the little box apart and to cut off one end of the pin. After that, and some more penetrating oil, I alternated between pulling with a vice grip and pushing (read: beating, smashing, pounding...) with a hammer and drift. I found it easier to rotate the shift rod with the shifter disconnected up front also.

I think that about does it. Just ask if you run into trouble.

I want to thank you guys for your diagnosis and help. Sure enough the coupler was damaged. It did not appear damaged initially but once I really go in there and had a good look I found the problem. Anyways. Thanks! a lot!
