Cant get out of 4th, any advice?

I think its a DG box, its from a low mileage 1.9 petrol, I was running a 1.7 diesel before, my box went and forward thinking thought I'd get a better geared box for the TDI install, gear changes were fine before engine swap, so yes it has a pin type bolt onto the gearbox that the rod goes over, and its straight!!



Back from test drive and its working, engines bloody lovely, it accelerates up Cornish hills beautifully, the gears still ain't right but it works, didn't get her oil done, but I reckon that may be low. Hopefully that'll be the answer, although I expect something else will go in the mean time!!

Will try again tmrw

the dg box cant have the pin , but rod through a hole

Aircooled and very early diesels only had the rod with pin . g/box casing are not interchangeable

82 is the rod and pin factort set up.

you need the code form the box , the 2.0 petrol dk code box is as good as you can get standard 4 or 5 speed ( is same as AAP 5speed 2.1 box in overal ratios)

this is what you will have hopefully , not the screamer 1600 petrol or diesel box.

1.7 and td diesels were not yet fitted on aricoooled era vans!

It's an original 82 1.6 diesel, one of the 1st watercooled, nightmare for getting parts, its a mix of t2 and t25 bits, luckily veedub machine are only down the road, and exchanges/refunds are no problem.

it had a 1.7 in it when I got it from a later van, I think the gearbox was the original, when it wanted to work no more I got the 4 speed petrol, it worked with the 1.7 the gear ratios and larger crown gear meant higher top speed.

I'm just looking at box oil levels for todays little job!
3l in a petrol box, 4l in a diesel 15mm below filler plug.

Or so it says, why would it be less in a petrol box, casings the same? Internals can't be much different?

the diesel box is on an angle compared to the flat petrol box as ell as the 5 speed having a larger nose

Yeah makes sense,

No time yesterday to check oil, so ill leave this thread until I next get time to potter!!

Right back on it, I had the gearbox out, drained oil, magnetic filler had no excessive metal, phew! I did however notice the input shaft was sliding out of the box, uh oh, bell housing off, found shaft circlip in bottom of box, bit surprised as I remember what a bugger it was to get on. So re installed shaft with new circlip, topped up gear oil and put back into van, bit of adjustment on the linkage to get it to engage 1st and 3rd and whooppeee, it flies again......until.......now I'm stuck in 3rd, properly stuck, disconnected selector rod, and tried changing it on the box, just to be sure it wasn't just the rod catching somewhere, stuck solid, just like before.....so what next, strip the box? can anyone direct me to a gearbox diag?
