berlingo 1.4i Van gearbox swaps

[stevem75]

The gearbox on the 1.4i TU3JP KFW is whining and I suspect it’s a well know 
Fault. It’s a MA 5 speed box code 20CP36.
I’m going to swap it for a Peugeot 206 KFW box 20CP09 or a KFU 20CP23
I assume these gearbox codes are for gear ratios but I don’t really know 
The bell housing looks the same.

Can anyone help and tell me if these replacements would be compatible 
As I’m not that knowledgeable on these gearboxes 

Any help would be greatly appreciated 

Thankyou

The 1.4 engine has a relatively low output and this is probably offset on the Berlingo by having a low ratio differential (5th gear feels about the same as a 'normal' 4th gear). The 'upside' is that many long hills can be taken in 4th gear.
The gear ratios - - first is certainly low to allow a reasonable getaway from rest .
Whether the saloon gearboxes that you are considering are similar in either respect - possibly not as they have less mass to shift from rest and are longer-legged on the motorway. This may not matter much if you don't carry any loads or tow anything, but could add to the feeling of being gutless if you do!

Continued.....well that was my theory ......but I've just found that the diff ratio appears the same at 4.06, but could also be 3.76 on the P. 5th gear ratio on the Peugeot is 0.77:1, as is the Berlingo.
Berlingo first gear is 3.64 :1, whereas the ratios I've found for the P include 3.41 as well as 3.63.

The big performance changer will be the diff ratio if its 3.76,
All info gathered from Mr Google !

Thanks for your reply. What I’m really asking is if these
2 different gearboxes would be compatible with the driveshafts
And clutch splines hole locations etc. From looking at pictures
It looks as thou they would but conformation from someone
Who is knowledgable would be great

Thanks

The 206 is listed as having a top speed of 171Km/h, while the Berlingo only gets t0 150.
So it's safe to assume that it has a slightly different top gear at lest.

Or the shed-shaped Berlingo runs out of puff and never revs out !

They rev out...

Not having had a 1.4 but this implies the gearing is much higher which for a van would to me be strange as I'd have expected a van to have lower gearing and to be revving its nuts off.

Any owners have a definitive viewpoint ?

Well, I guess anyone can have a view, but my '02 1.4 is certainly low geared and pretty steep hills can be managed in 4th gear, with 2000 rpm being the lowest it'll go before dropping down a gear. Makes it ideal for our very rural roads here in Ireland.
It does give it fair acceleration in 4th, but it actually feels more like it's in third.   It's probably something like 15mph per 1000 revs in 4th, and maybe 12mph per 1000 in 3rd, but I'll check that next time I'm out to give a 'definitive' answer.
The disparity between the Peugeot saloon and the van could be that the van max is in 4th, rather than 5th gear.

Well, a spin out today in my 2002 1.4 petrol came up with (almost) definitive numbers. Figures taken using rev counter and indicated speed, so as accurate as anyone else might be using the same approach.
Mph shown below per 1000 rpm.

1st Gear           5mph
2nd                  8mph
3rd                   13mph
4th                   17mph
5th                   21mph

70mph in 3rd       5400rpm
70mph in 4th       4200rpm
70mph in 5th       3350 rpm

Luckily I had my G-suit on.
