    What Is this 2004R Pump Mod?

    Just a quick follow up - screwed a plug into the hole and staked it. Went through the valve body using a transgo shift kit. Found several holes in the plate enlarged way more that the shift kit recommended so I replaced it and drilled per instructions. Got it all back together and pressures look...

    What Is this 2004R Pump Mod?

    That's exactly what I did - just hope there are no more surprises. The work was clean and well done that it did not catch my eye until I compared the pump section by section to another one. But I rarely go into an trans and then not too deep so not surprised that I missed it on the first time or...

    What Is this 2004R Pump Mod?

    Found this while looking for cause of low pressure. Can't make pressure sucking air... This was found in a trans that someone had been into but not ran. Its just a 1/4" hole that has been drilled and threaded that goes into the pump pickup passage just above where the pump neck extends into...

    Low pressure diagnostic help needed

    I'll definetly go over everything real well before buttoning it up and putting it back in. The guy that I got it from told me the pump had been drilled and it had something to do with tc lock-up. I saw where the seal drain had been drilled out and where to cage/check-ball was removed from the...

    Low pressure diagnostic help needed

    I think I found the problem. I cleaned everything up getting ready to do the final assembly on the pump and decided to pull the pump out of a core to compare it to. I found where a 1/4" hole had been drilled and tapped into the port that the filter slips up into. The hole was higher up than...

    Low pressure diagnostic help needed

    Just went through the pump. Check ball and spring for pressure relief both ok and no trash. Cleaned everything up and assembled the halves dry. Before putting the halves together I laid green plastigage over points on the slide, rotor, ring and vanes. Tightened it up and the took it apart again...

    Low pressure diagnostic help needed

    Hopefully someone can jump in and help me sort it out. The pump looks good but haven't pulled the pressure relief spring/checkball yet. Hoping there is trash or something under the ball or even the ball was left out. Other than the pump to body gasket being a little rough and the checkball out...

    Low pressure diagnostic help needed

    When I pulled the valvebody plate I found a checkball in that spot which is the wrong place. I was asking if it being there could have been the cause of low pressure on my gauge. The passage is labeled as 2nd clutch and with that ball being there, flow was blocked in both directions. Does...

    Low pressure diagnostic help needed

    Don't worry about insulting me, my transmission knowledge is limited and I can use all the help that I can get ..... The guy I got the tc from had several lying around(all were capped) and I got the one that he thought was the lower stall version to work well with my big engine. It looks like a...

    Low pressure diagnostic help needed

    Hello, its just a stock converter. I have fitted the pump into the converter and all seemed OK. I'll try the input shaft fit when I get to the shop. Is this the shaft that is different between the 27 and 30 spline version? Any ideas on the checkball out of place? Thanks, Bob

    Low pressure diagnostic help needed

    Found an extra checkball in the valvebody. The one for the tv exhaust was not in place which I understand from reading is usually left out. It has an extra one in the vb with location pointed to with red arrow in attached picture. It is on the opposite side of the plate of where the middle of...

    200r4 pump modifications?

    I used the 4th gear only lock-up set-up on a previous application. I just wired a rocker switch inline so that I could turn off the lock-up in situations where it was not wanted. I used a lighted switch with a green LED wired where it would light when the converter was locked. It was dim enough...

    Low pressure diagnostic help needed

    Got the trans out and started into it last night. Found a couple of interesting things but no obvious cause of low pressure. Any help finding cause of low line pressure would be greatly appreciated. Due to lack of room I can't remove just the transmission. It took about 3 hours to pull the...

    Transmission Upgrade - When, What, Why?

    Just my opinion but if EA is who you would use, call em. Let him know where you are and where you are going and from what I've read, he will shoot straight with you. A good rule of thumb I use for planning a build is to be sure each component will stand up to the most extreme stress that it will...

    Low pressure diagnostic help needed

    Thanks for the replies. I'm wondering if there is something after the pump that could not be working correctly that will bleed off pressure that I should look for while I'm in there. Hopefully when I go into it there will be something obvious. I'm comfortable with going into the pump, servos and...

    Low pressure diagnostic help needed

    Not sure from lack of responses if my problem is so basis that it doesn't deserve a response or what. This board does get a lot of respect and acknowledgement for being the best source on the 200-4R so opinions and ideas are welcome and appreciated. I'm decent at just about everything mechanical...

    Low pressure diagnostic help needed

    So I guess assuming I have engagement of the TC to the pump, I must have pump issues? Anything else to check before dropping the transmission out? Thanks, Bob

    Bad trans noises (with video) PLEASE HELP!

    Try importing the video into windows movie maker. IIRC, you can convert it there. Easiest thing may be to load it on youtube and post a link to it. Bob
