I ordered a custom 10" converter from BOC 2 weeks ago and installed it last thursday. I haven't driven the car but 30 miles with the vibration. The vibration occurs around 1100 rpm then smoothes then becomes prominent around 5k. I watched the converter while it was on a hoist today and it seems as if the front cover is loping as if it's out of round or was welded off center... I'm in the process of contacting BOC regarding the situation. Anybody else encounter any type of trouble such as this?
 
Thats strange. You installed the tc and bolted to pressure plate no problem though everything lined up
 
That's really weird.... it really sounds like a converter issue though.... I'm sure Lonnie will resolve the issue...

What stall did you get?
 
My bad flex plate

I do trans work professionally. I made sure everything was straight before bolting it up. Lonnie says it may have not been seated in the trans properly... Cleary not possible. converter nuts went on easily without cocking the converter to one side. I can't rule out that it's not the converter. Just this week we had a converter leak from the converter hub to the front cover welds. In my eyes anything could be wrong.

3200. I'm very dissapointed. WOOOO I cant wait to pull my trans out... AGAIN... Sh1t happens though.. thats life.
 
I'm sure that there will be lots of blaming you before the converter gets replace (if it is bad...) but that is how it goes...

3200 isn't really much more than stock, go big or go home :D

I'm thinking of doing a 4000rpm or maybe 4200rpm 9.5 from Circle D....

I feel for you man. I forget exactly how many times I had to pull my tc every time it was either the wrong one or wrong stall. I think it was three different converters and I know what you mean about lookin forward to pulling it again. I got it down to a science now. Last time pulled it and reinstalled one evening and test drove. Dont let them get the best of you. Don't settle for less than what you want. it will be worth it long term.

exactly. But I will fight to get it. I can get documented recipts of professional installation.

Perhaps the converter is not properly seated? I've seen this many times.

Proper installation of the torque converter (7902) requires full engagement of the converter hub in the pump gear. To accomplish this, the torque converter must be pushed and at the same time rotated through what feels like two "notches" or bumps.

The dimension from the pilot face on the converter to the face of the bell housing should be 7/16" to 9/16".

Not being seated properly will cause it to 'lope' off center and put undue thrust on the transmission.

I have to agree with JP here too.

not taking a shot at your mechanical skills, but as you said yourself "shyit happens"
 
He is a Ford Tech...

I have never understood how people could not seat the converter... I've done like 10-15 and never had an issue.

It goes in almost all the way and they don't know there is a second 'bump'. If I could find the exploded pictoral of the transmission, I would point it out.
 
I know I seated the converter properly. I spun it, it dropped down a little bit. Spun it some more, dropped down more until it couldn't go any further into the transmission. Lonnie said in an email he sent me the converter is likely destroyed or something to that matter. Thing is, today when I had the car up I pryed lightly between the converter and the pressure plate with the converter nuts off and the converter separately from the plate with no excessive pressure or binding. Also, as a preliminary check before completely tightening all bell bolts and converter nuts, I rocked the converter given the allowed space between the converter stud and the pressure plate hole, spinning freely and bindless in that the pp hole is larger than the stud... All signs point to the converter. But as with everything... They WILL try to blame the converter failure on installer.
 
I'm just gonna pull the trans tomorrow during lunch... Either way the converters gotta come out.
 
You will get to have some fun trying to get a refund if it is bad... I'd have it stalled up to like 3500 or maybe even 3700....

bummer

Come on KK, let the customer and the vendor "handle it".
no need to fan the flames...

If it turns out to be a defective product I dont doubt for a sec Lonnie will stand behind it.
BUT. if it turns out to be a improper install I wouldnt' expect Lonnie nor his convertor vendor to stand behind it.

let's wait til ALL the details are in before jumping on Lonnies nuts...m'kay?

Seriously, you dont make a good troll.. your too nice a guy to effectively troll someone.
(lol)
 
Ok, lets start out with a couple of things.

IF the converter went into both the transmission and the flexplate then it was definitely not out of round from the center and it would be impossible for the hub to be off. These are really tough to seat anyway because they have to go onto 2 things and into one more. First of all the stator inside the converter has to fit onto the stator support. Then the input shaft has to fit into the pilot. Finally the converter hub has to seat into the pump on the transmission. If ANY of those things are out of alignment then you are not going to seat the converter.

Then, if you got the converter onto the transmission and into the flexplate then you know that the front cover was straight as well. If it weren't then you would have had to fight it and wouldn't have been able to spin it freely as you say you could where there was proper clearance between the studs and holes.

On top of that, those converters are balanced on a REALLY expensive machine.

Now comes my really BIG problem with this thread.

yeh i know. Maybe I shouldve just told them its the wrong stall speed.

You have got to be f'n kidding me!!!

You want to tell us that you are a Ford tech and then you want to say something like that??? Come on man, you should know that to resolve a problem you need to be ABSOLUTELY honest and straightforward. Lying does nothing but make you the problem.

To so easily have said what you did on an open forum...

Well, it makes one wonder.

And I am kind of pissed off because of your attitude. Lonnie took the time to call me on his own time late last night to discuss your problem.

Think about that for a moment. A vendor taking up his family time after hours to look for ideas to help you.

Yeah, you need to head off and do a gut check in my opinion.

I’ve emailed you back with some instructions to check. I’m not going to just take anyone’s word that the product is bad until it is thoroughly checked out. I’ve been doing this for years and you wouldn’t believe how many times I’ve heard the words, professionally installed, Ford Tech, Ford Master Tech did the installation. Not trying in anyway to slam you or your capabilities so lets not go there. I just experienced a Ford dealership last week that called me 6 or more times a day for a week trying to install a fully built 4R75W and TC. They had the wrong turbine sensor and couldn’t get it installed in the case. I sent them the correct part numbers with pics and they refused to listen and decided to tear down the transmission because the sensor was too long and wouldn’t seat due to it hitting rev sun gear shell. The correct sensor is shorter. I could tell you many more but you get my point.

My bad flex plate

Not ruling that out either, it didn’t balloon, not that one with his setup.

I do trans work professionally. I made sure everything was straight before bolting it up. Lonnie says it may have not been seated in the trans properly... Cleary not possible. converter nuts went on easily without cocking the converter to one side. I can't rule out that it's not the converter. Just this week we had a converter leak from the converter hub to the front cover welds. In my eyes anything could be wrong.

I’m not ruling out anything at this point. But until everything is checked out I’m not going to just assume that it’s the TC. If everything checks out then you send me back the unit and I’ll have it checked out, replaced or repaired as needed. It’s really that simple, not a big deal like some are trying to make it. You have my warranty info http://www.blueovalchips.com/index.php?action=Trans_TC_warranty

I'm sure that there will be lots of blaming you before the converter gets replace (if it is bad...) but that is how it goes...

3200 isn't really much more than stock, go big or go home :D

Brandon, why you even here? People this guy has been following me around sites looking to try and slam and damage my reputation beside ruin my business by persuading people to go elsewhere because I don’t pass his customer service. What he was pissed at me about was the fact that I put my children’s custody battle before one of his emails. He actually admits it over here CVN thread So anything he posts is basically flaming when it comes to me.

And Brandon fully knows that this TC is custom built by Chris at Circle D for my company. He’s just trying to redirect you away from my business.

I feel for you man. I forget exactly how many times I had to pull my tc every time it was either the wrong one or wrong stall.

Last time pulled it and reinstalled one evening and test drove. Dont let them get the best of you. Don't settle for less than what you want. it will be worth it long term.

I don’t recall selling you any of my TCs, mind explaining yourself a little more?

exactly. But I will fight to get it. I can get documented recipts of professional installation.

You installed the TC you told me. So how can you "get" receipts for a professional install? I don’t cover install fees, fluids and so on. You won’t find anyone that does. Take a look at the warranty.

Perhaps the converter is not properly seated? I've seen this many times.

The dimension from the pilot face on the converter to the face of the bell housing should be 7/16" to 9/16".

Not being seated properly will cause it to 'lope' off center and put undue thrust on the transmission.

Same thing I said and was my first thoughts John. I couldn’t tell you how many don’t seat those TCs fully. As for the measurements, they are actually less but you were on the right track. If it wasn’t seated properly, 3 Clunks, not 2. The last one is more a big thud then it wasn’t seated. It not being fully seated will cause exactly what he is experiencing. It will also damage the TC, trans pump and put excessive pressure on the engine crank taking out the main thrust bearing. In just the past 2 weeks there has been 2 that have done this. It’s a very common install mistake and becomes costly.

You will get to have some fun trying to get a refund if it is bad... I'd have it stalled up to like 3500 or maybe even 3700....

Another poke Kid? Get over it, you seem to like hiding behind your keyboard and just tossing in more fuel.
yeh i know. Maybe I shouldve just told them its the wrong stall speed.

That’s pretty shady and shows the type of person you are. Read the warranty…..

Exactly
 
Lonnie's only got 23 posts and apparently has mastered the "multi quote" button. Some others around here should take note. :D
