Valvebouncer 2,389 Posted June 28, 2014 Hey guys, So I've got a BW35 in my ute at the moment that seems to shift well the only problem is the kick down cable is frayed and broken. I have a BW40 sitting in the garage with a kick down in it. My question is, can I pinch the cable out of the 40 and put it in the 35? Is there any other major difference between the boxes? I figure it's easier ( lazier) to ask here first rather than flood my garage with auto fluid leaving it looking like a murder scene. Share this post Link to post Share on other sites
Mr Polson 10,214 Posted June 28, 2014 Yep, cables are the same. Pretty sure the only real differences between the BW35 and 40 was slightly stronger internals, maybe different ratios? Share this post Link to post Share on other sites
Valvebouncer 2,389 Posted June 28, 2014 Cool thanks Mr Polson!! Ratios don't matter, it's slow anyway!! Share this post Link to post Share on other sites
XTREME KARTS XF 1,212 Posted June 29, 2014 Also on 35 models the cooling lines are on the drivers side on the box, not the passenger side like on 40 and M51 models Share this post Link to post Share on other sites
Valvebouncer 2,389 Posted June 29, 2014 Nah, just tore the 40 apart and was sussing out the 35 and their differences, both lines are on the passenger side. Share this post Link to post Share on other sites
Mr Polson 10,214 Posted June 29, 2014 Yeah, BW35s had the lines on passenger side. Share this post Link to post Share on other sites
Valvebouncer 2,389 Posted June 29, 2014 Well I've finished getting the kick down cable out of this BW40 anyone want it? Free-Last I knew it shifted fine, oil was pretty clean Share this post Link to post Share on other sites
Mr Polson 10,214 Posted June 29, 2014 Wasn't you putting it in your BW35? Hence the thread? Share this post Link to post Share on other sites
Valvebouncer 2,389 Posted June 29, 2014 No, pulling parts off it. I needed to know things like the kick down were interchangeable Share this post Link to post Share on other sites
xhadyboy 492 Posted October 8, 2015 Nah, Nah, just tore the 40 apart and was sussing out the 35 and their differences, both lines are on the passenger side. We have just been given a xf ute (that's 2 xf utes and 2 Xe's now) auto 255 km been sitting for 3 years Aug88 build. Just gave the fluid's a flush and took it for spin the auto is sliping a shudders into 3 rd. Topped up the tranny fluid but it needs a service. My young fella is going to take it to school and use the hoist. He is doing Yr 11 auto. VB's quote doesn't help with the differences. The kits for the 35 and 40 are different. Is there another way to I.D iT ? Share this post Link to post Share on other sites
Mr Polson 10,214 Posted October 8, 2015 Look on the side of the box (passenger side from memory) there should be a metal plate about halfway up it saying either Borg Warner Model 35 or Model 40. Probably needs the bands adjusting if slipping. What type of kit? If it's a filter and gasket they should be the same. Share this post Link to post Share on other sites
tpak addict 1,909 Posted October 9, 2015 I thought the only physical difference was the shifter was on the other side.... Share this post Link to post Share on other sites
xhadyboy 492 Posted October 22, 2015 The tranny has been identified it's called "luv u long time ",but seriously My son found a tag on the side that reads "Borg Warner Trans 40". Got the service kit from Repco included pan gasket filter and filter gasket $15. He brought out the bw 35 kit, it was covered in dust he said we cant get rid of these ones any more.

winton 399 Posted March 11, 2019 Hi all, I think i vaguely remember that the 35 was shorter then the 40. I'm I right or wrong? And dose anyone know what year ford changed from 35 to 40. I need a trans for a corty, I'm sure they had 35s, don't want to get a 40 and the tail shaft doesn't work. Cheers Share this post Link to post Share on other sites

Cheers Now that I think about it, I think I'm wrong and that the xmember mount is further back but the overall lengths are the same. If anyone could confirm or tell me different would be great Share this post Link to post Share on other sites
deankxf 20,266 Posted March 12, 2019 18 hours ago, winton said: shorter? i've seen 35s in shorter length in XY .. not sure about later models, only seen it once where a 40 or even 51 didn't take the same tailshaft length as 35.. (for all i know, it could have been from a sigma or something?) My brother dropped an XF 4.1 and bw 40 into his TE cortina i don't recall any difference.. (could be wrong, was 20yrs ago?)

Mostly just internal upgrades. I'm fairly sure tailshafts are the same. Think it was 82 or 83 the box changed? Share this post Link to post Share on other sites
winton 399 Posted March 12, 2019 Cheers guys, that clears up my confusion. About 20years ago I swapped a 40 from an xf in to an xr, I need to used the xf tail shaft, because from memory the 35 was shorter, but pretty sure I read somewhere else that 35 and 40 were same, so yeah confused about why I had to use the xf tail shaft. With the corty tail shaft i was worried about the length. Share this post Link to post Share on other sites
