Default Anyone have a service manual that covers the 440T4 trans???

Here I am putting my new trans together for my STE and since I wasn't the one who disassembled it (I was given the trans back, the car back, and boxes full of trans parts back seperately from the incompetant trans shop) I am not sure what springs go where in the accumulators and whatnot and I really need a diagram or something showing where it needs to go. So does anyone have a service manual for that trans? This is all I need to be able to slide this thing in the car and I would really like to get it done since I can't see myself driving the TA in the winter, and can't afford to with these gas prices!

Thanks.

Shawn

I've got it, but there are a many year differences. Even 88 to 89, and I believe there were more from 90 to 91. You have a year for the transmission? Because an 88 isn't going to work for an 89, because they have the differences marked in my FSM and there are quite a few.

Did the transmission shop just take the transmission apart then just throw everything in a box? No offense, but you'll never have that transmission running again if that is the case. I'm sorry, but if the parts didn't get damaged rustling around in that box, they won't get put together right [no matter how hard you try]. Hopefully that isn't your case.

Its a 1990 trans, since my STE is a 1990 and thats what it came off of, that would make sense. I know there are going to be many differences from year to year, but I don't think the springs for the shift accumulators are going to change much from year to year and thats all i really need to know, that and how everything bolts in there and they don't typically do too many major changes like that from year to year. A service manual for a bonneville is going to be different than one for a turbo gp anyways, but all I need is the diagrams to see what needs to go in the two accumulators that are right above the filter.

If they took it apart and then threw everything in a box this would do me no good...the trans was really screwed up, which is what happens when you have 350ft.lbs. and you use a trans rated for 220ft.lbs... Just about every single part in the trans needed to be replaced. The boxes had all the good hard parts from the tranny and a rebuild kit along with the new replacement hard parts and then all the misc. snap rings and the little stuff like the accumulator springs (which is the stuff I'm not sure about). I rebuilt the trans myself with pretty much all new parts, but now that I got all the rotating components and everything in I just need to know how to assemble all this miscellanious little stuff that is left. I'm not gonna throw a trans together with broken parts. I go to an automotive college, its not like I haven't taken an Auto trans class. I'm not saying its gonna work perfectly or at all, just that I didn't exactly rush through it like you did with your headgaskets...(no offense) I would just get the specs at school but I'm home right now (since thats where the car is) so there is no sense in going to school just to get a diagram, especially since its 180 miles away and I wouldn't be able to get it until Monday.

If you have a diagram that shows how all that stuff goes (basically everything that can be installed with just having the pan removed) then I would appreciate it if you could post it so I can at least see how it was for the year you have the manual for because I can probably figure it out from there.

Thanks.

Can download the service manual for a 1990 Reatta at http://www.reatta.net/docs.html - it uses the same "C" 3800 and 440T4 (though in 90 it was called a 4T60). Will have to request permission.

The file is in PDF and is quite large.

Thank you, I signed up, I'll download the file as soon as I get my username/password from them. The name is 4t60 in 1990 but it is still the same trans (440T4) so it doesn't really matter.

I still would appreciate any diagrams anyone can get me please...

DorkBoy, I have Don'* 1989 Service Manual. I have no idea what'* inside a transmission.

Here' what I can figure out from the pictures...

You're talking about the "Accumulator Cover and Governor Pipes" right? Here'* how it says to put that back together...

Install:
1. Accumulator pins (111 and 115) into case.
2. Accumulator springs (112 and 116) into case, the 3-4 spring is larger than the 1-2. (3-4 is closer to flywheel)
3. Accumulator pistons (114 and 11 onto pins.
4. Spring (147) into case pocket.
5. Lube oil pipe retainer (109) onto lube pipe (110) and "O" ring (10 onto retainer.
6. Lube oil pipe (110) into case - pipe must be installed into the driven sprocket support lube hole.
7. Spacer plate (120) and new gaskets (119) onto the case.

Assemble:
1. Governor screen (126) into governor feed pipe (125) - closed end first (accumulator cover side of pipe)
2. Apply Loctite cup plug sealant No. 271 around ends of governor oil pipes (124 and 125) that into cover and retainer.
3. Oil pipes (123, 124, and 125) into accumulator cover (121).
4. Oil pipes (124 and 125) into governor retainer.

Install:
1. Oil scavenger scoop and bolts (106 and 107).
2. Accumulator cover, pipes, and governor retainer (129) as an assembly (121 - 129) onto the case - lube pipe (123) must be installed into the final drive internal gear.
3. Bolts (122 and 130). Bolts (130) are longer. Torque bolts to 27Nm 20 lbs. ft.
4. New filter lip seal (57) into case (16).
5. Filter (5 into case.
6. Gasket (63) onto case.
7. Magnet (66) - position over dimple in bottom pan.
8. Install bottom pan (59) and attaching bolts (60). Torque bolts to 13Nm 10 lbs. ft.

That making sense?
