Transmission issue


Good evening all!! Update. The problem returned this weekend. We went to dinner and no problem. Came out and started the boat and no forward gear on the port side. Me mechanic is still saying I have to rebuild the tranny. Another guy thinks is electrical. Tomorrow he will run all the circuits and see if there are any shorts. We have a lond trip to Long Island planned this weekend. Not sure if I want to trust it. Ugh. Any ideas. Thanks again.
 
Update Again.. We switched the solenoid modules on the transmission control block from forward to reverse. This caused the boat not to go into reverse. This tells me that the transmission is fine but there is some kind of wiring issue or short. It only happens when the boat is warm and turned off and restarted. Weird. Another electrical "expert" is coming today to look at the EDC and the ECU on the engine. I'll let you know how it goes. By the way -- I'm not cancelling plans this weekend since I know its not the tranny itself. Thanks..
 
Hi jlazzfp...I am giving my boat guy all of our conversation and will see if I am as lucky as you! Wish me luck!

Divergirl I wish you luck. Trying to get a Volvo guy down here to troubleshoot the electrical problem. What is your problem exactly?
 
My problem is exactly the problem you are having. When I have run the boat (same year, model, & engines as your boat) for a while, the port engine does not engage immediately in forward but does in reverse. I see your last post was 9/2 and you were getting a Volvo mechanic to take a look. Anything new? My boat guy tells me he would feel more comfortable with a Volvo guy servicing my boat so, nothing has been done or explored on my boat as I have been reading your posts and trying to learn from what you are experiencing. I find it very interesting that we have the exact same problem with the exact same boat.

Wishing you resolution.

Hi divergirl. Over all this time I still have not been able to get a mechanic to come from a Volvo dealer. I'm trying to get one this week. I will keep you updated. Thankfully the boat works fine and have had no other issues once it's in gear. Do you have any idea if a mechanic will check yours out soon. I'd like to know what yours thinks too !! Keep me updated. It's really weird same boat same problem. Thanks.
 
If I recall correctly, the Volvo EDC shift system can be re-sequenced. Had to do it a couple times on my 330SS. Unfortunately I can't remember where to find the sequencing menu.
 
Hi Gurryman.. Can you describe what you mean by re-sequenced. I'm not sure even where to look for something like that. I remember reading that you can possibly adjust the delay in the shift timing but not sure if that's what you mean. The problem is so sporadic I think it's an electrical short somewhere, bc it only happens when the boat is warm. Any info would be helpful. Trying to get a Volvo mechanic to the boat is harder than pulling teeth!!!! Thanks
 
jlazzfp....my boat guy is Brazilian and I have a hard time talking to him on the phone due to his English skills or, lack thereof. I had copied and pasted the conversation threads from the forum and sent them to him a few weeks ago. He called me yesterday to say that he has two trained Volvo mechanics working for him now and they all went to Bimini a few weeks ago to deal with this exact problem. He said he is able to resolve this problem and seems (from what I could decipher from the phone call) knowledgeable about it however, he is booked and can't get to my boat until Oct. I think you are in the New York area, right? We have a lot of Volvo shops down here in south Florida. The one which was recommended to me by Volvo Penta to resolve the safety recall regarding the wiring harness for the SB engine, I would use again but I am thinking my regular boat guy will be less expensive. They are Marine International Diesels, Inc. in Ft. Lauderdale and, I am saying that without really knowing what they charge as Volvo Penta paid for the safety recall repairs.

Don't worry....we will get this sorted out soon. I will keep you in my loop and me yours!

Hi divergirl. Yes I am in th NY area. A friend took the boat out today and said the boat did it even more frequently than in the past. I'm really bummed since my season is almost over. Did your mechanic ever say if it was electronic or mechanical? Is it an easy fix? Just so frustrated that I can't even get someone to look at it!! Ugh !
Gurryman.. Not sure if that will help and my EDC controls don't look like that. I'd be too afraid to try it without a Volvo mechanic. Thanks.
 
Hi jlazzfp,

I feel your frustration for sure. One nice thing about living in south Florida is that we get to boat all year and, of course, there are tons of marine mechanics down here, Volvo and otherwise. My guy, and as I said he is hard to understand unless you are talking with him face to face, said he knows what the problem is and he will be glad to fix it however, he is booked until Oct. He did not imply that it was anything very complicated...just that he did not have time to get to it until next month. You might want to call the Volvo mechanics I used for the safety recall 1 year ago. Maybe they can refer you to someone in your area. The guy who came to my boat is Jefory Burke, Marine Int'l Diesels, 954-761-1086, midijef@gmail.com. I have no doubt we will get resolution soon. I think I might email Jef and see if he can provide any feedback like..."yes, I have seen this problem several times and it is.......".

Back to you soon.

Hi divergirl. It would be great if you could find out little details and a little feedback from him. Just an idea which way to go. I actually had to cancel diner plans this weekend since I'm too afraid to use the boat now. The one thing I'm sure of its not the transmission itself. We went out Labor Day weekend and hit at least 6 foot seas and the tranny held perfectly. I also don't want to put the boat away for the winter with the problem still there. Thanks for the feedback!!!
 
Hi jlazzfp....I reached out to Jef Burke and the following is his reply:

Great to hear from you;
A few things come to mind with reference to this topic, I would research thefollowing below (in no specific order) after considering that there was anupdate issued many years ago for a connection issue that could create thisissue.
1- Confirm the engagement using the manual override feature on the shiftsolenoid. This will satisfy if the issue is signal related from the lever orwithin the marine gear.
2- It is possible the throttle calibration could be the culprit however,it's not likely for that calibration to simply just go away.
3- The throttle lever (position sensor) could also be suspect, a calibrationwould clear that up however.
4- I would not rely on the coincedince of your vessel and the one in NYChave the same issue. Not saying it couldn't happen however.
There are other test that can be performed on board that would negate orshed more light on this scenario.
Please advise.
 
So, there was a connection issue update. Did you receive that update from Volvo Penta? I have asked him when he can come to my dock and perform the tests he mentions above. A bit of progress!
 
Hi Divergirl. Here is what was done. We switched the wires from one lever to the other on the helm -- the trnsmission then would not go into reverse showing that the transmission is not the issue. We can manually override the solenoid on the transmission itself so it goes into gear every time ruling out again a transmission issue. We switched the Y connectors from the EDC of the engine to transmissions of both engines -- it still failed on the port engine. This means that the Y connector (that goes to the solenoid) is not the problem. I already changed the forward solenoid on the transmission and it didn't fix the problem. My mechanic changed the pressure support bearing on the transmission which didn't fix the problem. I spoke to the Volvo dealer that services my area. He said that the mechanic is now working on a similar problem on another boat same year!! Getting weirder every day. He is supposed to come to my boat next Wednesday. Can you give me the hull ID of your boat?. I'm really interested to see if they are close together. Maybe this problem is specific to when our boats were built. See what your mechanic says. I will keep you informed. Thank for the info.
 
Wow....talk about ferreting out problems. The hull# is TNRD2002C202. I am going to call the Int'l Marine Diesels office on Monday and schedule some time for Jef Burke to come to my dock. My boat is in my backyard which makes it pretty convenient all the way around but, especially for service issues. And, that is way to coincidental that there is another of our boats, same year, same problem. Thanks for your info and we will plod on!
 
Hi, tried to take Divergirl out today and was not far from my dock and the port forward stopped working all together. Came back....nightmare docking scenario. One thing I have not asked you does the engine rev up without the tranny engaging in forward? My revs up but no engagement. Reverse is still working fine. So, is your port reving buy not engaging?
 
Hi divergirl. I think we have different controls. I don't have single lever port and starboard. I have separate transmission and throttle levers. You must have the Volvo single lever controls. So my engine can't rev unless I increase throttle on the right side. The bonus is the Volvo mechanic is coming tomorrow!!!!! I will keep you updated. Thanks.
 
Hi...Jef Burke from Marine Int'l is coming to my dock either tomorrow afternoon or Thurs morning so, we will be able to compare notes. Did you take a look at our hull numbers? So, you do not have the electronic drives, right? Sheese...I cannot wait to find out what this is and I know you can't either.
