2004r 2-3 flare

[czimpel]

Does anyone have an idea of why I have a 2-3 flare when manually shifting, but a super hard quick shift when left in drive?

Extreme Automatics Stage 2 less than 1000 miles, but 3 years old. Fluid looks and smells good, no junk in the pan.

Probably a leak in one of the vb circuits. Auto sends the fluid different than where it is sent with the shifter being moved. I'll look at my principles of operation manual and get back with a better answer.

Clear as mud.

Yeah, fluid goes lots of different places inside there.

What manual is that? Where did you get it?

 

[TurboBob]

thats the "Principles of Operation" book, from GM.

first, get a pressure gauge and see whats happening to the line pressure.

is this something you just recently discovered, or was it ok and then got bad?

you should also check with your trans builder.

I watched eBay until one I could afford popped up. I think it is a great resource if you want to know the how and the what inside the 2004r.

I wish I had the color one.

I think it's always been there. I don't drive the car enough to figure out that I had the issue until I took it to the track. I then thought I had burnt it up. I dropped the pan, and everything looked and smelled normal. No debris or clutch material. I then had a bad turbo which took me a couple months to finally get the money to purchase. Finally got it back together and just happened to notice that the 2-3 shift problem was better when I had it in D, but it would flare when manually shifting.

Problem with the whole thing is that I purchased this trans about 3 years ago, so my 1 year warranty is over.

I just figured this out, and figured it's my fault for catching this so long after purchase! I know he's super busy as well. I'll send him a PM.

A heads-up on the 200-4R Principles of Operation GM book. It is still available from Helm. Ordered it yesterday, it shipped out today. I waited to post until it shipped in case it came back as 'no longer available' or such.

Navigate the site some until a search box shows up and drop this code into it:

HM2004RPO

The price is decent, the shipping and handling doubled it
