whats your description of lag? does it try to die or anything when you put it in reverse? or are you speaking more of it has a bad delay and revs up barely moving?

The 2nd. Some revs before the indicator finally goes to D the. Drives no problem. Never really stalls but I did manage to stall it reversing with wheel locked loading the power steering sometimes.

You need to get a pressure gauge after it. sounds like something is causing low fluid pressure.

after my gear selector goes not shifting from D 3 2 1 back and forth sparactically, It just defaults to 2 and I the truck act like its in Neutral and I have to coast to a stop. Shut the truck down for 5 secs, then Gears are back. I noticed REVerse even goes until I can restart the truck.

So my truck is in some sort of limp mode... Checked my wirings, to make sure connections was good. soldered and heatshrunk everything to be safe. Same problem still. The only thing I have not dont yet, it swap out the RELAY mod. I only use 1 relay on my 80e swap. So Ill give that a try today to see if it works.

Mine shifter indicator acts funny most the time but i can get it to show the right gear.. i need to rotate it some..
but the only thing mine does funny is when its cold, i back up to turn around in the driveway and it takes a second for Drive to engage from reverse.. But if i warm it up it works just fine.
and first gear is really loud
