here is my situation. Im putting in a rebuilt 700r4. I have my used one beside me and my old converter. With the old converter on, measuring from the mounting surface on the bellhousing with a straight edge to the torque converter mounting bolts, I get 1 inch. Same for both transmissions. If you try with the new converter, I only can get 3/4 inch.

Both converters measure the same from the tip of the snout to the mounting pad. Converter is the correct spline. Pump notches appear to be exactly the same size. I dont have a caliper to completely confirm.

Put some grease on the center shaft (no splines) and put the converter up on it. It lacks 1/4 inch from going all the way in. Which makes sense since the mounting plate is only at 3/4. What is keeping the converter from going in that last 1/4? Any help? ANy ideas?

thanks

Pretty sure Im counting this one as a defective part. Just dont see anything else that could cause it. I left the company a message. I really wish I had another set of shafts to try to put down into the converter to try and pinpoint what the problem is. Hopefully the company will make things right. Or I will find out how big of an idiot I really am. Oh well, everything happens for a reason

 

keep spinning it and pushing it onto the trans, its probably just not on all the way yet

 

I wish it was that simple. There is an interference somewhere.The more you push, the harder it is to get back out. Everything is lining up and engaging. Its just not engaging far enough. Contacting the converter company tomorrow to see what we can work out. Im wondering if there is a slight taper to either the center shaft in the converter or the notches in the converter snout.

 

I agree. Spin it and and try to jiggle it while spinning. Sometimes there just a pita to get seated.

 

sounds stupid but is the spline count the same on both transmissions cuz there was an early and a later R4 been down that road.did you try your old converter to see if it slides all the way into pump?

 

Im really telling ya guys, Its not from a lack of spinning and turning. Atleast I think, lol. 2 of us tried multiple times on two transmissions and it would never go in far enough. And it was always very tight to get off. But the old converter would go right on both of the trans. It is so hard to get compared to the old converter, that I dont really think its me. Though it could be.

Yes spline count is correct. 30 spline. The converter will drop fine on the first 2 drops. Then you can feel it start to drop on the 3, but it wont. The pump engages, but it wont slide on down.

I would file just a hair on the pump knotches on the snout, but I dont want to void any warranty before I can talk to the company.

 

Whos converter is it Had an ACC that was f*****d up right outof the box can you measure inside diameter of hub alot of these converter are just remanufactured and depending how it died the first time there could be some heat distortion just took one out of a glide that layed the fins over after a dozen runs and the hub was blue from the heat

 

lol. its an ACC too. One of their 10" units. I just cant really catch a break. I searched and searched online for anyone asking about them. Never heard anything negative. Didnt hear much, but nothing negative. I hope that their customer service is good.

Now the question is do I try to get an exchange or a refund and go with a more expensive converter.

 

they replaced mine no questions asked but the white crayon part number on converter was wrong,and the thing had fluid in it right out of the box hope you didnt get that one.took me a little while to figure out though.Now im using Trans specialties CompetitionTH350 and converter broke 3 r4s and said thats it,I think the guys name is Nelson at ACC youll talk to,Is the the notch beveled where it engages the pump?

 

yes it is beveled at the notch. This one was dry. Not now though, has a qt of my Amsoil fluid in it now.

Im really not sure what the problem is. What did you think of the other converter when you got it back? Did they go ahead and send one out or did they wait until they received the other one back? Im just trying to decide which direction to go. Refund or replacement.

 

I sent it back and the new one came pretty quick it worked fine until we broke trans again now it sits in a box. I wouldnt spend alot of money on a converter for an r4 unless you built an extremely strong trans cuz eventually youll get tired of fixin the r4s I looked at trans specialties r4s before i got the th350 and thats the only trans they wont warrant so that kind of changed my mind,

 

well thats good to hear atleast. I'll try to get ahold of them today and see what we can work out.

 

spoke with them on the phone. Great customer service. Going to send it back today to let them check it out. Hopefully I can get this straightened out without much more delays.

 

sent it back. It got there on thursday. Called them friday. "It was in line"

Called monday. Emailed the guy the code they sent me to keep track of the converter. Never replied. Called this morning. They was going to go right back and check on it then call me back. That was 2 hours ago.

How hard is it really to check and see if something is right or not? Mine is simple, try to put it in a transmission. Wont take more then 5 minutes. Then come back and say, yep you are right, somethings not right with it. Would you like a refund or a new unit?"

And what the heck do they mean by saying its inline to be worked on? Do they have so many NEW parts returned that there is a line? Since mine is new it should be moved to the front of the line ahead of any restalls etc.

Getting aggrevated. Going to call back in a few minutes. Im waiting on this one thing. Everything else is ready to go. I miss my car.

End Rant.

 

Got the converter back last friday.

Slipped right on.

Amazing how it wouldnt go on before, they claim nothing was wrong, but when it came back it worked.

 

Its amazing how that works,well ill be dealing with that next week when the4l60e shows up for the 97 SS
