Before I bought the car, the previous owner had the transmission work done.
So, reading the receipt I have no idea what much of it means. I have a flare up/smal slip from 2-3rd and I am installing a vette servo to (hopefully) help this out.
So if you can tell me what these things do that were replaced I would really appreciate it.
Master (something) kit (can't read it) 201 dollars
Front pump bushing 8.45
2-4 Band 42.30
Filter
Re-built torque converter
Fluid.
I know what the last three things are.
The transmission was removed and re-installed for this work. SO I am wondering what do these things mean.
What does 2-4 band do???
I am really not sure what the Master (I can't read the middle word on the receipt) KIT, with part number K7700LS means.
I just need some help on these two things.

 

Here is the pick of the receipt.
I am thinking that, there is something I don't know about thus really making me unable to read this...
And few different eyes seeing it would help.

 

i see front pump bushing, and rebuilt torque converter, new 2-4 band, filter, cant read the first one, looks like master something kit


sounds like a few of the std things to do in a standard stock rebuild to me


good luck

 

Does 2-4 band have anything to do with 2-3 shifts???

 

the 2-4 band is for 2nd and 4th gear. 2-3 upshift is preformed by the clutches in the input shaft housing assy. That and the valves in the valve body

 

So, in other words the servo wouldn't have much to do with the 2-3 upshift??? Cuz thats where the tranny is slipping!>????

 

Master O/H kit.

 

Whats that??? Overhaul kit???

Engines I know, transmissions I don't.

 

Oh, I was just reading on the raptor transmissions that performance servos make 1-2 and 2-3 shifts firmer. So, I guess I will see what happens once the vetter servo is in.

 

Yup

 

The servo won't do anything for your 2-3 shift, it only engages the 2nd gear band which is your 1-2 shift. Your 2-3 shift is controlled by the 3rd and 4th gear clutch pack.....and unfortunately it's the week point in the 700-r4. This is where builders like to add the "extra clutches", use the red clutches, and koleen steels to try to get the tranny to live.

Sounds like yours could be on it's way out.

 

Ok, well, I know there might be something wrong with my tranny, but just to bandaid it for now, I am thinking of installing the servo.

I went to TCI transmission, and was reading about servos. They had ones for 700r4 which and I quote
"...also eliminates common 2nd to 3rd flare problems..."
I would paste the whole thing, but for some reason I cant select any of the letters.
So, right now thats my only choice if I want to keep the tranny in the car and operating. I've seen cars slip and its nasty, compared to my 100-200rpm
"Flare" when shifting to 3rd (half way on the throttle ofcorse).

Don't mean to argue here, but the servo's gotta do something to that 2-3 shift. It could be just higher preassure?? I am just starting to study transmissions (spent waaay too much time studying engines with my previous car ).

 

The vette servo physically attaches to the 2nd gear band, thats all it pushes on. The 4th gear servo is also located in the same bore which they also make a performance version of.

The flare they are talking of is when you disengage one gear before you engage the other. The vette servo should in theory disengage quicker than stock so that might help that type of flare. The "flare" you are describing sounds an awful lot like slipping clutches to me. I've experience the other type of flare and it feels like you go to neutral real quick, then drop into the next gear. Great for chirping the tires into 3rd, but like I said if it feels mushy into 3rd then your clutches are shot. The only bandaid I've heard of is to run type F fluid since it's a bit thicker than type III. What ever you do don't change the fluid, the burnt clutch material that's floating around in the fluid is actually helping the clutches hold. We've gotten another 20k miles out of my dads truck this way. Just go easy on it while you plan your rebuild.

 

OK, well, I've seen cars slip, and they usually revv up higher and kinda wait untill the gear is caught.
Mine feels like, for a second its dissengaged, than it engages again. It actually feels like it goes to neutral than to the gear. Its defenetly different then slipping. Thats why I was asking all the questions around here. All in all, I have a hard time telling if its bad or anything so we'll see if the servo works. I think it will (cuz I think thats the problem), if not I'll just throw in some Lucas in there ( I already bought it)
Thanks BMONTESS
Oh, it defenetly doesnt feel mushy into third, once it gets it its pretty hard.

 

A larger 2nd servo reduces the 2-3 flair. This is from the 2/4 band being released later. The flair is caused by the 2/4 band being pushed off before the 3/4 clutches are being applied. The tranny ends up in neutral for a split second. It's the whole timing thing for the 2-3 shift.

The opposite of this, where the 2/4 band pushes off too late, the tranny will actually lock up in two gears at once. This can be felt as the vehicle stops accelerating for an instant followed by a clunk from the rear. The noise is from the driveline slack being taken back up.

Thank you sir.
