Question for any mechanics

[Greyman 28,284]

Son has a Vauxhall combo van it’s the one with the 17 Isuzu lump in it, trouble being the 13 cdti is the more popular model and I,m after sticking a new gearbox in it for him this weekend so my query to the better informed is are the two running the same box. And is it interchangeable cheers in advance

Drove a 1.7 dti for 11 years brilliant little vans, wouldn't of thought they'd share the same gearbox with the 1.3 but I could be wrong.

the 1.7 can have the f17 gearbox aswell i think but just take the box off and check numbers because the bell housings can be different aswell

That’s right, the f23 was fitted in the old vectra’s and Astra’s, f17 was fitted in the corsa’s zafira’s, I think the bell housing is different, I seem to remember it’s where the starter motor mounts

I thought the starter motor was on the back of the f17 bell housing and on the front of the f23 or the other way round

i had a young lad who was swapping a box in a fiat van ( same box ) at my last mechanic job and came and said to me there was no hole for the starter, fiat had sent the wrong box and he had managed to fit it without noticing, thick as a whale omelet, no wonder I got out of it

Thanks for the answers chaps much appreciated, one more thing then can you not just swap the bell housing from one to the other or are the shafts different as chid suggested .??

Petrol sierra box will fit perfect on a diesel sierra but input shaft is to small and doesn't enter the flywheel .

i’m sure some had f17 boxes on the 1.7 

i was meaning an f17 or 23 can have differnet bell housing so not all f17 are the same like for like you can always swap the bell housing over but more work and the sub  frame shite the vauxhalls lol

I’ve just mentioned it to my mate he said the drive shafts are different, the selector is different and depending on what vehicle it has come from depends what bell housing is fitted, so in short as Chid said it won’t fit
