    700R4 1-2 shift issue, please help!

    Update: Considering … the task it is to remove the TC and transmission and work on that beast in my limited shop space; I have decided to remove the valve body only and work on it on my small shop table without having all the extra parts around cluttering my space. If things get complicated...

    700R4 1-2 shift issue, please help!

    Great idea, I will then drain the fluid, remove the pan and check the tv cable, plunger and valve cycling, or lack of, before taking it down. Now Im waiting for parts to arrive in one or two weeks. Going back to the lockup topic... I read somewhere that the one prong pressure switch is for...

    700R4 1-2 shift issue, please help!

    I found and old (last year) photo of the valve body when I changed the oil pan and servo. Confirmed to have a Type 1 (two hole A, B) valve body. Therefore, according to the Transgo site, I need the SK 700 kit which has the plate gaskets. In addition, I need a new plate and pan gasket as...

    700R4 1-2 shift issue, please help!

    See images for TV Plunger roll pin location and for TV Valve roll pin location. The later requires the valve body to be removed. BTW, the previously posted Sonnax kit is for the TV Plunger, Sleeve and spring.. not for the TV valve. Don't now if the plunger also gets stuck, but from what...

    700R4 1-2 shift issue, please help!

    Thanks! Will order the transgo jr kit soon. I saw a video "by Automatic Transmission" "DRTranny" on you tube installing this kit. It does require to remove the valve body to get to the rear roll pin on the TV valve, the other/first TV plunger roll pin is accessible without removing the valve...

    700R4 1-2 shift issue, please help!

    I've never removed the actual valve body. Is this something I can do under the truck upside down and not loose any check balls or springs that may be in it after taking out all its bolts? Also, I found this on another forum that may be helpful to someone trying to diagnose a stuck TV...

    700R4 1-2 shift issue, please help!

    Hi Matt, I don't see your posted instructions but found them in the Sonnax site. Are you referring to the 77966-94K kit? Based on the instructions you are right, its only a retaining pin. However, is there enough room between the case and the valve/plunger area to slide it out? See attached...

    700R4 1-2 shift issue, please help!

    I am hoping dropping the valve body is not required, that would force me to drop the transmission and transfer case. Does anyone have experience with doing the tv valve/plunger upgrade? Any recommended part/kit numbers to purchase?

    700R4 1-2 shift issue, please help!

    Thanks Matt. I have no idea if the TV plunger is stuck. I do know the TV cable with the associated hook and return spring inside the transmission case is ok (returning with spring action etc). But I guess that doesn't say much about the plunger itself. I know there's a tv plunger upgrade...

    700R4 1-2 shift issue, please help!

    Ok this is the next update: Ran the truck just now with the original C weights 15.1 grams and Black and Blue springs (heaviest from the bunch). Result: Now its shifting 1-2 consistently at 25mph. Didn't get up to speed to check the 2-3-4 shift. However I would like to get the 1-2 shift down to...

    700R4 1-2 shift issue, please help!

    Update: I weighed the weights I have out of the governor, and the original C weights are heavier than the A and B weights in the K018 kit. So the first weight change I did to the heavier kit weights (A, B) actually were lighter than the original setup. Original C weights - 15.1 grams Kit A...

    700R4 1-2 shift issue, please help!

    Hi, I'm having issues with the 700R4 on my 84' K10. Ok let me provide details of what I've done and where I'm at. Initial issue: Not shifting from 1st to 2nd until 30mph. Engine screams at those rpms (don’t know the rpms, don’t have a tachometer installed), but based on the engine noise it...

    Welding or Lunchbox front Diff locker for K10?

    Yes, that's basically the use I will have for it, boat ramps straight up/down and getting unstuck. When on 2x4 I always have both hubs unlocked ("free" position). Any suggestions on quality/brand for a mini spool, or are all the steel alloys used within the same design basically equally good...

    Welding or Lunchbox front Diff locker for K10?

    For some reason I'm not getting reply notifications on my email for this thread. Anyways, Thank you all for the suggestions. I also researched the options I have before welding and found what its called a "mini spool", which range from 70$ to 130-150 for the more expensive Yukon. This will...

    Milky oil after 1984 K10 305 top end rebuild.

    I think I got it now and don't want to imagine having to go through this again. I believe it was a combination of poor initial resurface job and also at some point a leaking intake gasket. Lost track of what I found each time I disassembled the top end. This is the third time I've installed the...

    Welding or Lunchbox front Diff locker for K10?

    Hi, I have a beat up K10 (1984) that I've been fixing up. It has a 305 sbc, 700R4 trans and transfer case with wheel lock front hubs. Anyways the other day I was messing around a steep dirt track testing the 4x4 which works great. However on one section a front tire lost traction and obviously...

    Milky oil after 1984 K10 305 top end rebuild.

    Update: didn't want to leave you hanging after the March 2 post. Well after that installation with the .120 intake gasket crap show I still got milky oil. Decided to take the heads off and get them pressure tested (they passed) also noticed that the head at cyl 6 had porosity where the fire...
