904 Valvebody Overhaul

[@boxer71c55]

Excellent channel and video Gary, very easy to follow and understand. Looking forward to watching more.

[@GaryFerraro]

Thank you

[@boxer71c55]

I think I'm missing some checkballs Gary. I followed your vid exactly to disassemble when I lifted my top half off and it had no checkballs in it. Scoured the net to no avail. Thanks

[@ws678ta]

Very clear, and concise video for those willing to learn. ... Thanks.

[@GaryFerraro]

Thanks Steve

[@Almeshtages3]

Good work Gary and Good answer

+‫احمد محمد‬‎ Thank you

[@Almeshtages3]

Hi Gary : I want ask you question about the fluids and material or items they used to clean the parts of trans and valve body its could ( cleaning solvent) (Mineral spirits) Can you tell me what is this items and where can we find

[@GaryFerraro]

+‫احمد محمد‬‎ It is mineral spirits, i get mine from a supplier, not sure where your located, but do you have home depot anywhere?

[@ZENIGMATV]

Old valve bodies are basically fluid brains. Wish I could afford an after market electronic controlled trans. Pulling my 904 out tomorrow,lost only reverse.

[@GaryFerraro]

If 3rd is ok, then you have a band problem

[@issaalazzabi6087]

thanks for the vid gary can you tell why did you sand the valve body and what girt that stone has

[@GaryFerraro]

+issa alazzabi I flat sand to take any high spots out, so i have no cross leaks, not sure of the grit but its a fine stone and not course

[@rayvantassel5455]

Thanks good job / can a stock valve body be converted over to reverse manual?? Hp bang tires cherp

[@GaryFerraro]

If there is a kit available, check Transgo web site

[@ineedmine1]

Hi Gary. What size checkball is the steel and also the Torlon checkball that you put underneath the separator plate?

[@7paperboy]

Are these transmissions similar to the 32re? I need to rebuild one and cant find any videos on them. Thank you for your great videos bud.

[@GaryFerraro]

Yes they are

[@issaalazzabi6087]

hi gary gary how you doing i am in process of rebuilding u241e can you tell me what things that i should look for

[@GaryFerraro]

+issa alazzabi Make sure the front planet pinion gears are not loose. What is this trans doing that your doing a rebuild? Gary

[@meowmix3525]

Great video. You might try adding more description to reach a wider audience. It took me a few hours of reading before I found that the 32rh is the same as a999, and basically the same as the a904. TorqueFlite as well so now I’m way too educated on this transmission lol.

[@GaryFerraro]

Ok, will do, thank you for watching

[@meowmix3525]

@@GaryFerraro Again these videos are great. I had a successful replacement on my E4OD from your videos and this is helpful as well. I will say it was a PITA to get this Jeep valve body off. The shift linkage and selector rod did not just pop out as guides suggested. Had to wiggle driveshaft hopefully this helps someone.

[@GaryFerraro]

@@meowmix3525 I pop out the E clip and leave the rod in the trans. Thanks for watching, glad i could help out

[@meowmix3525]

@@GaryFerraro that sounds much better than the experience I had. Now I just have to find a missing check ball

[@GaryFerraro]

@@meowmix3525 The ball for the detents?

[@ScanMan79]

Where do you find the plastic check ball? Does it come in the overhaul kits or does it have its own part number? This will be my first rebuild attempt on an auto trans (A904 out of an 87 Dodge b250 van) What brand would you recommend for the kit? Any help would be greatly appreciated! Thanks for your time.

[@GaryFerraro]

Checkballs are in the valvebody, just put them back. Kit type is TransTec

[@ScanMan79]

@@GaryFerraro Thanks for the reply! I guess I wasn't very clear with my first question. My bad. :) In your video, you had mentioned that you trade out the steel checkball for the reverse to a plastic one to prevent damage to the separator plate. That's what I was curious about. Does that plastic checkball come in the rebuild kits or where do you get that plastic one? Thanks again!

[@GaryFerraro]

@@ScanMan79 Oh, gotcha, i looked on a couple of websites and i do not see them, not sure about part number, few more sites i have to check, going to see if my supplier sells them

[@moeshouse575]

many years ago i found i could lesson a harsh rev by going to low with the gear leaver first.

[@GaryFerraro]

Thanks for the tip

[@TheChewyWun]

Do you know if this can be done without removing the trans from the car? 71 Dart with a 340/904 combination. Seems like you should be able to get to everything when you remove the pan, unless the parking linkage can't be disengaged.

[@GaryFerraro]

Valvebody should come down

[@TheChewyWun]

Thanks, any reason just replacing it isn't a good idea instead of rebuilding it? It's my daily driver so being down as little as possible would be great.

[@GaryFerraro]

If you can find one, installing another valvebody will work

[@TheChewyWun]

Many thanks, I'll have a look around.

[@GaryFerraro]

welcome

[@issaalazzabi6087]

gary i have a question about 09g solenoid is it okay to remove the top cap that holds the spring and put it back on

[@karanbudhrani9856]

what rebuild kit did you use

[@GaryFerraro]

I use only TransTec

[@luisanabolivar9939]

hi gary; my jeep wagoneer has a transmission 904 whose activation of the lock up is hydraulic, it is not electric, I adapt this transmission to my wagoneer, it was a rambler, but activates the lock up at very low speed (40 km 28 miles), each Once it is activated, the whole vehicle trembles and the converter is damaged after three months. My question is what can I do to block the activation of the lock-up? or what can I do so that this activation is done at a higher speed? or would it be possible to install some device to activate it manually? here in venezuela buying another box is very difficult with the economic crisis, we all struggle daily to be able to buy food, I adapted this box because they gave it to me, Gary so that you have an idea of the crisis here in Venezuela, the 9 pots of oil for transmission are more expensive than the transmission used, 4 new tires are worth more than my car, what's that? thanks in advance for your answer !!

[@GaryFerraro]

If you look at the main valvebody, do you have a tube connecting the main valvebody to the auxiliary valvebody?

[@luisanabolivar9939]

yes, it is a tube in the form of s ?, this transmission 904 repaired a month ago with a mechanical friend who only repairs transmissions, he made maintenance to the valve body, I saw that tube

[@luisanabolivar9939]

yes, it is connected

[@GaryFerraro]

ok, pull the valvebody and take that tube out. I think i use to crimp it, but just leave it out and see what you have

[@luisanabolivar9939]

ok, I take out that tube, and the two holes that are left, I cover them up? or do I leave them open?

[@SmokeyBear363]

hey man i just got done rebuilding a 32rh trans for my 01 wrangler and am having issues shifting into third. reverse works, 2 and 1 work as well. i can drive it up to 50 mph at around 3300 rpms but it wont go into third, rpms jump as if its looking for third but just wont shift. what do you think it could be?

[@hutch430]

Thank you for the video. My 904 does shift into reverse pretty harshly. You think it's the separator plate? Otherwise the transmission works perfectly. I looked. Where can I find a separator plate?

[@GaryFerraro]

Did you see that the hole in the plate is beat up where the check ball sits

[@hutch430]

I haven't opened it up yet. Let's say it is can I buy a new one? Or am I regulated to do what you did in the video?

[@GaryFerraro]

I believe they are available, let me ask my supplier, where are you located?

[@hutch430]

I am in Los Angeles. Thank you for your help.

[@GaryFerraro]

Ok, let me talk to my supplier and see what he has, what is the year make and model(he's going to ask me) If he has, he can ship to you

[@ahmadsaker64]

what's up man. I need help with my tf904 that's in my 73 charger I've rebuilt it by the book and it was amazing for a day then one morning I lost forward drive but still have a strong reverse ... can you help?

[@GaryFerraro]

Sounds like issue with the foward clutch(drum with the input shaft), maybe drop the pan see if you can see anything

[@psicopatalucifer]

hello Gary I am going to rebuild the transmission from a 07 Saturn relay 3.9L v6 ( transmission 4T65E model M15) I am going to buy the Deluxe kit from the company PA CARGO inc. ( pa cargo MRK8400U Deluxe kit ) only $127.89 dollars my question is do you use this brand of transmission parts in the past .? if so do you like them .? also do you have any tip for me in this transmission rebuild .? thanks so much in anticipation for your response.

[@GaryFerraro]

+john CR I buy parts from pa cargo, but whos overhaul kit is it, Is it a trans tec kit? or a precision kit? Gary

[@haimodelu]

Please get a better camera or phone, your perfect knowledge must be accompanied by a better video quality, 1080p will be great.

[@issaalazzabi6087]

gary i have a question about 09g solenoid is it okay to remove the top cap that holds the spring and put it back on

[@GaryFerraro]

+issa alazzabi Do you mean at the end of the snout?

[@issaalazzabi6087]

+Gary Ferraro yes

[@GaryFerraro]

+issa alazzabi I honestly would not remove that, i believe thats part of how the solenoid is calibrated.
