Gearbox for 253/308

[pro_gmh]

Hey fellas, just curious is the TH350 3speed auto replaceable with the TH700 4speed? and is goin to the TH700 any benifiet? which is a better box?

[Goon]

You get better top speed on a manual, great accel with an auto

Its upto you really and want you want out of it, or if you prefer to drive manual or an auto.

[pro_gmh]

im always after accel more than top speed, altho i would like to be able to acheive atleast 160-180 if i wanted to. but for me im all about accel, so unless i had the $$$ for a tiptronic i would probs stay with an auto.

I just wanted to know if the th700 used in the vn's etc would be a good option. if they are a stroner box compared to the th350 and if they would bolt up to the back of a 308 without an adation plate, new xmember etc.

[POVRTY]

im pretty sure the bellhousing patterns are the same i think the bolt up ok.... the turbo 700 has 4 gears aswell. but i think its got some electronics to figure out. not sure if its any stronger though

[pro_gmh]

im not worreid bout the electronics, that easy stuff. i was just wondering bout the bellhousing and the crossmember. would i need a new tailshaft? is the box longer?

[atrail308]

yeah, i believe the tailshaft is a different length, and remember it has a flange fitting to the pinion of the diff... as for the bolt pattern, it will fit if you got a turbo block, you'll prob need the VN starter motor and rear x-member tho...

by the way, they are both an auto trans...

[atrail308]

but... on a 3rd note, the T700 is a lot weaker than the T350, ur only advantage will be the overdrive...

[pro_gmh]

overdrive only came on the vr up didnt it?

[atrail308]

All turbo 700's have a 4th gear, the TH700 in the VN's up is equivilent to a
T180 used in the states, just with a 4th gear...

[atrail308]

sorry, i correct myself, the trimatic is called the T180 in the US, the T700 is equiv. to a T200, not much stronger than a stock trimatic, but a lot weaker than a T350...
