Torque Converter Installations

Ever since my new billet converter was installed, at cruising speeds when it locks up, it shakes and causes a driveline vibration.
Otherwise, my transmission performs fine. Shifts fine and smooth, both up and downshifts. Its only when it locks up it has this ridiculous shudder/driveline vibration.
If I drive more spirited, it does not do it at all. Only when cruising at around 45mph.
Could it be the converter?
Is there any way to install a converter incorrectly?
Any ideas?
Thanks

I figured my gap from flywheel to converter already, the no fluid in the converter is worrying me.
Thanks!

Converter bolts should be M10x1.5

Help! TC is engaging the pump but won't fully seat. And once it's on the pump, it's very hard to pull back off. It seems like it's binding on the pump tabs. It's a remanufactured TC. Could the notches that engage the pump be too small to fully engage the pump? I'm at a loss here.

Next time put the pump on the converter before installation. The rebuilder should have done that on a spare pump as a check in my opinion.

The pump bushing probably went in crooked. With what you said the pump needs to be taken out and taken apart, inspected and repaired.

I'll be doing this for the first time this weekend. My question is if the spacing between the torque converter and flex plate is greater then 3/16" it has to be shimmed. Does the transmission have to come back out in order to put in a spacer.
Does anyone have a pic of a spacer/washer they used?

Spacers/washers are pretty simple concepts...just make sure all 3 are equal. Some cheap hardware store washers can vary in thickness if you just pull any random 3 out of the bin.
I never pull the trans again to install shims...I just use a dab of transjel (you can use vaseline) to stick the shim to the flexplate...then rotate it and put my bolt in. Works like a charm

Was having issues with TC not fully seating on pump. It would engage the pump and then get stuck. Very hard to get the TC back off.
Rebuilder had me exchange the TC for another one. Same issue.
Now says its the input shaft that has a slight twist to it and that was causing the TC to get stuck. All I see is dollar signs!

Look at the splines on the turbine-shaft.
Do they look damaged to you?
They snap more often then anything else.
I would also look at the splines of the stator support coming out of the pump.

Builder pooped the install of the pump bushing. Doesn't want to admit.
I don't know that I've ever seen the splines on a 60 twist...I've seen them break or wear the splines right off but not twist.
Good luck, remember to fill us in on what the final fix is

Hey guys, I got it done. Other then the poly motor mounts keeping the engine/trans from sagging, then install went fine. I did have to shim for proper pullout however. My initial feel is that it's going to be an absolute blast to drive.
I can't wait to put my foot in it.
Quick question on getting the fluid level right. What determines warm from hot. I got it close but I don't want to overfill it.
