2-3 Tranny Flare ?

[MtDew]

Hey Guys,

I read several of the post on this site and determined, with the help of the posters, that I might have an issue with the valve body gasket or bolts. I took the truck to my local mechanic and he pulled the pan and "snugged" the bolts up. He also told me that the gasket looked good from what he could tell.

When I picked the truck up, the mechanic said he hardly tightened the bolts a quarter turn and he doubted that it would work. The good news is that the problem is significantly better. The flare is almost non-existent now. However, I still don't think the tranny is quite right. It still feels a little sluggish shifting between 2 - 3 even though the flare is gone.

Any ideas where I can go from here and is it common for a bolt to be less than a quarter turn loose to cause this 2-3 flare??

Thanks!!

You can't always see a torn valve body gasket with the valve body installed in the car. You may still have a problem with it, and the tightening of the bolts may just be masking it temporarily.

Get yourself am ATSG transmission manual. (Got mine from JC Whitney) Pick up both the valve body and seperator plate gaskets. Set yourself up with a nice clean well lit work space, a couple cans of brake cleaner, torque wrench and gasket scraper and knock that sucker out. I'd bet money you've got a blown VB gasket. It's not that hard. Just lock the door, get rid of the kids and pay very close attention.

Might also pick up a can of teflon lube at the place you buy the gaskets for disassembly and post cleaning re-assembly... even though it is a little different, the thread on the A4LD valve body rebuild with pictures will be a good instructional manual for the how to's... just looks different, principles are the same.

(hint: someone get me a 5R and I'll do a VB rebuild diary ! <g> - right after the 4R70W Diary, and BW 1354 TCase Diary)

Fyi

I ordered the kit (new blowoff valve and separator plate) that Eneurb was kind enough to list in another post. It's purpose is to reroute the pressure and prevent the valve body gaskets from blowing in the future.

I haven't installed it yet, and so can't comment on the results, but for a total cost of about $35, I thought it was a good idea to have on hand when I drop the pan on mine.

Hey ! How about a photo thread like TN_Explorer did? WOuld be VERY helpful for other on here! I'll help ya construct it if'n you will do one.

I have a stack of 5r55 valve bodies, but I'm sure the shipping costs would be catastophic!

Glacier, if you were speaking to me, thanks for the offer. Unfortunately it's going to be several weeks before I can tackle this job. I have all the parts on hand, just not the time. (Nor the inclination to spend a Sat afternoon in a very cold garage with ATF dripping in my face, if you want the truth.... )

If this kit is indeed the cure for the 2-3 flare, it will be great news. (The kit itself won't do anything that new gaskets won't, but it's purpose is to prevent the gaskets from blowing out again, as I understand it.)
