Yes they are supposed to be the same size. You accidently used 3 of the longer 3/4 accumulator bolts and some are probably making contact with the band causing your binding issue.

So the longer bolts that hold a stock 3/4 accumulator onto the valve body are 08675533 and have an UHL of 2.5", so ditch those longer ones once you confirm that the UHL is 2.5" for those longer ones.
The bolts that you want to secure the pressure manifold switch to the valve body have an 8mm head are m6x1x55 and are part number 8676222
For reference, the valve body bolts with the 10mm head are m6x1x55 and part number 11515262

So get 3 of these: https://www.rockauto.com/en/parts/ac...ody+bolt,18158 from your supplier of choice.

Rock auto shipping sucks as of late, so maybe someone has some that they can just ship you. Or you may be able to secure some locally at an ACE hardware or Fastenal.

 

Oh man if this turns out to be the issue, that would be fantastic. I'll run to ace to see what they have now!

 

You could go sloppy mechanic on it and cut/grind down the long bolts but not sure if you'll get enough thread engagement.

 

I have seen this problem on 4L60E valve bodies but did not think it was a thing on the 4l80e. i was going to post about it but wrote it off as useless information as the 4L80E uses all the same length bolts, aside from the pressure manifold bolts which are same length but 8 mm head.

 

The Accumulator bolts are the 8mm hex head with the larger diameter flange. The PSM bolts are the 8mm hex head and the smaller flange.

 

Any updates on this? If you only put in the short bolts in the PSM and left the 3 longer bolts out with the VB bolted up, did the output shaft rotate in both directions?

 

The 3 new bolts are supposed to come in on thursday. I havent put in the 3 correct sized bolts in, but when i tightened up the valve body with all the 10mm bolts and left the PMS bolts out, the driveshaft turned both ways in neutral.Fingers crossed. I will let you know as soon as i can test it out. It will probably be on saturday!

 

Good deal! You should be good to go then once the other bolts go in.

 

The correct bolts fixed it! No more bind! Thanks for all the help.

I adjusted the braided dipstick to be the right depth. Unfortunately it is super hard to read. I can't tell if it is over full or not even on the stick. Fun stuff

 

Good to know!!! Thanks for the follow up!!!

 

Thanks for all the help!

 

all the lokar wire type dipsticks ive used had a chunk of aluminum on the end. maybe look into doing something like that?
anymore I shy away from flexible tube dipsticks unless there is no other option.
also some well-placed P-clamps will help get consistent fluid readings
