A340E ( 30-40LE ) Rebuild

[@taylormcgiffin812]

Thanks so much for the thorough video, mine is in bits at the moment waiting on parts, this will help alot.

[@CurmudgeonTransmission]

Glad I could help. Good luck on your build. Thanks for watching.

[@ScottFoley-r7e]

I am rebuilding a A340F. My kit came with 5 forward clutches but I had 6 in the trans. Also the kit did not come with the 3 little filters for the valve body. any suggestions?

[@CurmudgeonTransmission]

I don't know who you bought your kit from but you might contact them. WIT and Transtar sell them separately. Links are in the description. As far as the filters go. If they are not ripped you can clean them and reuse them. Also they can be left out with no issues.

[@ScottFoley-r7e]

@@CurmudgeonTransmission - Thank you. if the truck moves when I put it back in you saved me $5,500.

[@ScottFoley-r7e]

Thanks for your help, the transmission works great. unfortunetly the rebuilt torq converter from NAPA failed within a week. it has a loud whirling sound when in drive and reverse. would you suggest I take a replacement from Napa. I also found a new one from "toyota overstock" for $1,100. the Napa converter was $270.

[@CurmudgeonTransmission]

@@ScottFoley-r7e Personally I would get one from Precision of New Hampton. Link is in the description.

[@justingatlin268]

This an excellent video and I greatly appreciate your making it. I used it to help me in rebuilding the aw4 for my Jeep. I noticed you mention the metal sealing rings. What trouble did you have when you changed them? Also, have you experienced any trouble with replacement split seals not sealing even though they are properly installed? Thanks again

[@CurmudgeonTransmission]

To be honest, I don't remember. Back when I first started and went to the seminars, ATSG told us that.So, I have never replaced them. Never had a problem with the others other than fitment. Check them in their bore first. Allowed .009 gap at most..

[@Gloccthejocc]

Where does the thrust washer with two prongues go? It looks similar to the bottom one on the planetary gear.

[@CurmudgeonTransmission]

Are we talking about a plastic one? The flat one goes on the back of the planetary. The dished one goes under the sprag that is in the planetary.

[@lastonkuluunda480]

excellent video and your good presentation

[@CurmudgeonTransmission]

Thanks

[@AmpdEngineering]

Hi, do you know what the valve body separator plate code id is for your sequoia here? The 2wd? Also the casting #? I need to know so I can have the proper new valve body sent in for my sequoia.

[@CurmudgeonTransmission]

8938 on the VB for both TV cable and solenoid style. C9 on the separator plate if you have a throttle cable, E17 if it has a solenoid.

[@dap-qm1bs]

Amazing job you are a genius, thank you very much 👍👍👍

[@CurmudgeonTransmission]

Thanks for watching.

[@celicablues]

Hopefully this translates well to the 4wd transmission. Im going to be rebuilding mine soon, thank you for this! I can tell you have experience. Only with lots of it can you pick through piles of parts and get it together like nothing. What grease do you use for the orings? Will any moly grease work for holding parts in place like you are doing?

[@CurmudgeonTransmission]

It is the same except the output shaft and tail housing are different. You are not going to want to use moly grease. I use Lubegard assembly goo. It is specially formulated for transmissions. I use the blue for o-rings and green to hold bearings etc. in place. If you don't want to use that you can use transmission fluid for lube and vaseline to hold stuff in place. However, it is not as thick as the green and will not hold them in place as well.

[@celicablues]

@@CurmudgeonTransmission Wow thank you for the quick reply! I'll take a look at those you recommended

[@celicablues]

I do have one more question, why measure the bolt lengths? Is that to check for stretching? Or to make sure they don't bottom out?

[@CurmudgeonTransmission]

Make sure they don't bottom out.

[@johncarvino567]

Thanks for watching them. You do have to keep an eye out for it but it rarely looses any.

[@BobKaufman-v9m]

I am about to work on a 1989 4wd A340H transmission. It has started to have no reverse in 2wd backing uphill. It will go if in 4wd low. I was planning (hoping) a master rebuild kit for the transmission and transfer case will cure what ails it. Any speculations of what might have gone wrong in there? This was a great video and while the year is different than mine I am guessing things are pretty similar inside. Thanks again!

[@CurmudgeonTransmission]

Only in 2wd and only uphill would make me think it is in the transfer case. Exactly where, not sure. Maybe range fork.

[@BobKaufman-v9m]

@@CurmudgeonTransmission it has now started to 'shudder' a bit when starting out backing up in 4wd Low. Driving back from town the other day and climbing a grade the transmission did not seem as 'responsive' as in harder to maintain a 45 mph up the grade. I guess the thing to do is get it out of the rig and cleaned up and disassembled. Any obvious signs you would suggest looking for? I read somewhere on the internet that a possible reason it is working in 4wd low is that it takes less pressure to run the reverse gear and that the clutch is slipping at higher pressure. I don't have the expertise to evaluate the truth of that statement. Thanks so much for getting back to me!

[@CurmudgeonTransmission]

I think what they meant was less torque in 4 low. It actually needs more pressure to work reverse than forward. I think it will be obvious what happened when you get in there. I would imagine it started off as the rubber seals getting hard and loosing pressure. It's what usually happens with Toyota's, besides the planetaries coming apart.

[@pointlinesquare]

Hi, the first snap ring that goes back in with the beveled edge (at 25:50) i notice you specified bevel toward front which is consistent with the atsg aw4 instructions. Im rebuilding a toyota 30-43le which is similar, has the beveled snap ring, but the toyota instructions do not specify which way the bevel goes and i chose to install the bevel facing back. Im now several steps past that. Would you go back and flip it? The toyota instructions have been pretty clear otherwise, have they left this out because it doesn't actually matter?

[@CurmudgeonTransmission]

You should go back and flip it over. Thanks for watching.

[@pointlinesquare]

@@CurmudgeonTransmission Thanks I did👍 Another detail I noticed in your process (a bit too late for me), with the manual shift rod you left the rooster comb, spring clip, and "spacer" sleeve in place. I had already removed that spacer per the Toyota instructions... to anybody else doing this job for the 1st time: a replacement is not included in the rebuild kit! I believe it's purpose is just to make extra sure the spring pin never falls out. I will be replacing it with a widget from my collection.

[@AlbertsZiemelis]

What manufacturer (brand) do you recommend for rebuild - gasket kits, discs, friction discs, bushings and so on? I mean A30-40LE gearbox particularly.

[@CurmudgeonTransmission]

Hi , thanks for the great video it was alot of help i just rebuilt my a340 from my 02 tacoma 4wd but i am having trouble with overdrive clearance and burnt overdrive up on first drive and it would'nt even shift into 4th but came back to find it burnt the clutches up im not sure whats happening and would greatly appreciate some insight Thank you . Alex.

[@CurmudgeonTransmission]

Are they the overdrive brake (large ones in the case) or overdrive direct (ones in the drum)? What was your clearance?

[@TheStrlx]

@@CurmudgeonTransmission These are the overdrive brake clutches large ones in the drum Mine is a 4 pack clutches with 4 .079 steels and a pressure plate with a 37 stamped on it It came out with a 079 steel/ friction alternating with a presssure plate on top ATSG states a few combos and piston travels based on specific models My piston travel was 1.43 mm Spec 1.4-1.7 mm per ATSG I burnt up overdrive after only driving a couple of miles and it wouldn’t even shift into 4th gear it threw a p0755 code which had me drop the pan and instantly could smell the burnt and I dropped the valve body and could see the massive clearance and burnt OD brake clutches I’m wondering if something is wrong in my valve body or what I could have done wrong Thanks in advance

[@CurmudgeonTransmission]

@@TheStrlx Clearance was fine. We're they burnt before. I think you got a sprag backwards or check ball in the wrong spot.

[@TheStrlx]

@@CurmudgeonTransmissionno they were not burnt before the reason for the rebuild is the overdrive planetary came apart Upon further investigation The OD direct clutches are melted together also I have decided to tear the transmission down completely from this point I had 11 check balls and took a photo of their locations and am confident they are back in the right spot but I cannot find a diagram with 11 check balls 10/12 so is it possible I lost one or is their a 11 check ball valve body that I didn’t find the diagram for I was using sonnax vacuum test pdf for my info . Kind Regards

[@CurmudgeonTransmission]

Give me the casting number on both halves of the VB and the separator plate number and I will see if I have the locations. There are so many variations on this valve body it is not even funny.

[@geraldvineyard2271]

Great video but I sat and watched the whole thing and it didn’t cover what I was interested in which was the shift solenoids. I have a 1998 Toyota Tacoma 4 wheel drive that is giving problems. Sometimes when I put it in drive it doesn’t take the gear. I can start off in low and shift to second then drive and it works fine even when pulling a trailer. It’s pulling a PO753 code. Any suggestions?

[@CurmudgeonTransmission]

Check out the 1 hour 30 mark in the video. P0753 is shift solenoid A electrical. Should measure 10-14 Ohms. Can also check them using 12 volts. Should click. Shift solenoid 1 or A is at the bottom, second one up from the bottom is SSB or S2. Next one up is the line pressure. Top one is TCC, S3 or SSC, depending on who is labeling it. Usually it is a bad solenoid. occassionally it is a bad wire. Never seen a bad computer. DO NOT use Rostra or any cheap Chinese solenoids on this unit. You will be doing them over and over and over.

[@geraldvineyard2271]

Thanks

[@geraldvineyard2271]

One more question, you said not to use cheap solenoids for this transmission repair so what brand would you recommend for this application? Thanks in advance for any help

I have a question to the creator and would appreciate a response: I followed every step that you gave but at the time of installing in the tundra in the vehicle, it only drives forward even in nutral and it does go in reverse no matter what, could you explain where I could have gone wrong that caused this?

[@CurmudgeonTransmission]

I believe you probably missed the manual valve alignment on the linkage.

[@vlogitroy7599]

Great video! One question, i see you dont torque the bolts. Is it okay if I dont torque them? Does it make a difference?

[@CurmudgeonTransmission]

I get reamed about that all the time. I have been using the same impact for about 25 years now. I know what it feels and sounds like when I am tightening bolts. If you are not confident in your abilities to do that you should use a torque wrench. There are times I still do.

[@vlogitroy7599]

@@CurmudgeonTransmission one more question. The Valve Body, mine has the seperator plate and a black gasket. Do I need to replace the black gasket? I see yours doesnt have one. I have the same transmission as the on in the video. I accendtly made a small crack on the paper blac gasket and toyota is saying it going to take a month to get it.

[@CurmudgeonTransmission]

I don't use gaskets on my Toyota's. They will work fine without them. If you have the ability flat sand both surfaces and the separator plate. If you use a gasket, it is best to match every single hole on a Toyota as there are so many ones with just slight differences in them. Just the gasket being swollen can get you in trouble with them.

[@vlogitroy7599]

Ahhh okay. So you wouldn't recommend putting transmission gasket maker on the small crack on the black gasket instead right. It's better to just remove the entire black gasket and just use the separator plate by itself.

[@CurmudgeonTransmission]

No, I would not do that. If you don't want to take the valve body apart and take the whole thing off, you can trim all the gasket off with a razor blade all the way around, so it sits flat.

[@AlbertsZiemelis]

Why you didn't soak the friction discs for 15 min in the ATF before assembly?

[@CurmudgeonTransmission]

I get asked this alot. Never seen a difference one way or the other, so I don't do it. If you feel the need by all means do it. Did it when I first started, been building for 37 years now and not had any issues with it. Thanks for watching.
