alright im swappin in a s5 trans into a s4. i was told to change the mounts so it would fit. so i set both transmissions side by side and took off the mounts. now i cant remember which one is which. is there any way to tell? i mean they have some slight differences but anyone know how to identify which one is which.

 

lol! are they manual?

 

yes

 

anyone? id kinda like to try and finish this swap today.

 

The S5 has some ribs on the case that the S4 doesn't.

 

the trannies are swappable, you dont need to change the mounts. I think the only difference is one of the connectors for the wiring

 

nah i remember which trans is which just not the mounts. i cant remember which mount is the s5 and which one is the s4. sorry for the confusion

 

isnt the s4 supposed to have the best tranny for all 7's?

why do the swap?

 

I would have said the S5 is better, the case is stiffer, the rest is the same AFIK.

The crossmembers are different, use the one that fits the tranny, they both bolt to the chassis the same way.

 

cuz the s4 trans is dead.

 

i belive the crossmembers are located in different spots.

 

I'm just going off of memory here, so the details may not be 100% accurate. I know for sure that the crossmembers bolt to the car the same way and bolt to the transmissions in different ways.

The angle of the Y blocks are different and the way they bolt to the transmission and crossmember is different. On one tranny there bolted directly to the tranny, on the other there's a bracket that goes between the tranny and the Y blocks (or was it between the Y blocks and the crossmember?). Anyway, you need to use the correct crossmember for the transmission and it'll bolt right up to the chassis.

 

oops youre right, disregard my previous post. When i switched trannies, , i used the original mounts

 

s5 tranny will fit just fine, wires are the same but i think there might be less connectors, i'm putting my s5 tranny in tonight or tomorrow, i fried a few bearings in my s4, its pretty bad, leaking oil onto the exhaust too . . .

 

Yea, that's why I switched too, mine leaked. It made a pretty good smoke show one day right after I filled it, in retrospect it was probably slightly overfilled. It's nice to no longer have the smell of transmission fluid associated with driving the car.
