I need the ratio's and final drive for these two box's can anyone help, Ive looked but cant find any info?

TY754VN4AA and TY754VN6AA both 03/04 on.

 

Ok Im pretty sure the final drive is 3.9 due to being VN but 1st to 5th ratio's??

 

3.454 = 1st
1.947
1.366
0.972
0.738

1.1:1 drops, 3.9 front diff, 3.545 rear diff - Viscous centre

ALL Uk VN *** boxes have the same ratios every time no matter TY752 or TY754.

That do ya ?

David to bring up an old thread mate....looking for some advice for a mate. ...he has done 3rd gear in on his Ty754 and were wondering could that third gear be replaced with a know good one from a Ty752 box?

 

No can't be done. The 752 gears and 754 gears are not interchangeable. For several reasons. It is possible to do, but would entail an entire swap of gears and synchro's and hubs for all gears as they sit differently for throw and the synchro teeth spacing between 752 and 754 does not match.

Best to quit wile you're ahead.

Hi Mate,

could you tell me if the rear diff from a JDM import bug gearbox number TY754BBAA would work on my uk bug gearbox TY754VN4AA
cheers Sy

 

No it won't, you need the matching diff for a UK car gearbox. We have stock, Call me and we'll get you sorted out.
