I got a lq4 from a 04 2500 chevy truck.. I swapped the flywheel from the ls1 to the lq4 cause the TQ was not lining up with the lq4 flywheel.... quick swap and tq bolted on fine..... after swap was done and the moment to start it up the started would grind and at times the it would turn over.....Turned on just fine, but when i put it into gear it didnt get any gears...... i cheaked fuild and it was full.... Next i diconnected one of the tanny coolers and it had no pressure.... so the means the the tranny pump broke during the installment.... I got under the car and notice why the starter would grind..... the flywheel was about 3/8 out.... the flywheel flage is not flush with the rear main seal....guessing do to the extra 3/8 stickout of the crank cause the tranny pump to break during the install........... MY ? IS THE A WAY TO MAKE THE 4L60E FIT WITH MY YANK SS4000?..... or do I need to get a different TQ or do I have to run a 4l80e?.... If so can I use my Yank ss4000 on the 4l80.... and before anyone says maybe its a lq4 off a 99-00... Its not cause it came with alum 317 heads and it uses the newer style head bolts that started it 04+............ can I just bolt on a 350-400 turbo tranny?

question, why did you take the lq4 flywheel off for a ls1 flywheel?? All you had to do was enlongate the holes on the original flywheel to make it bolt up to your torque converter...very simple to do then you could've just kept everything in tact like it was prior UNLESS it didnt come with the flywheel..

pretty sure the lq4 and ls1 flywheel is a different size i think...I could be wrong but i think they are different somewhere in there! Just use the lq4 flywheel, enlongate 3 of the holes on the flywheel and drive that thing!

its easier to just swap out flywheel..... still what should i do about the longer flage... should i get an out TQ or just run a different tranny

My lq4 bolted strait in my car with no issue. Lq4 fly wheel still on motor. No grinding or elongating holes ( maybe needed in some case?)
Important: what vehical did your lq4 come from? If it had a 4l80 behind it I believe you can simply remove the spacer and put an fbody fly wheel on it, or buy a TCI or B&M and use you yank to 4l60E

I have a picture of how far the flywheel sticks out from behind the rear main cover.... I just don't know how to post pictures.is it possible for someone to send me the email so I can send a picture and they can post it up for me..... anybody

And it it hard to remove the spacer..... what do u use to remove it.... the motor came out of an 04 2500 not the HD and it had the 4l80 bolted to it....

My lq4 is a 2003. It came from a denalli, so it had a 4l60e behind it. No modification was needed at all.
I'll sen you a pm
