Title: Help needed with gearbox problem '97 GC
Post by: ukturbo2000 on May 26, 2012, 06:21:55 PM
Went to Bagshot today, had a great day until i got stuck in 3ft of water and filled the car with water. All was ok then after a short while the coolant temp went to about 105 degrees and gearbox stopped changing down when you stopped, so basically you were trying to pull away in top gear from standstill. This was intermittent until finally all drive was lost. looks like it was pushjing gearbox fluid out from dipstick. Car was running like a dream until 15 - 20 minutes after waterlogging. Any ideas what the problem could be.

No water in gearbox, i've also checked for a crushed oil cooler pipe. Anyone know the location of the gearbox ecu ? any other ideas to try ?

If it was pushing gearbox oil out of the dipstick science dictates something else has got in....suggest change gearbox oil and filter which I think it has..

are you sure the water never got in to box and are you sure the rad is clear and is the water in the rad clean or has the water gone in to the auto box via the cooler

i have a not good feeling about this

awaiting arrival of new filter, then going to flush complete system including torque converter by the cooler pipe removal method on youtube. No emulsified oil came out when box was drained, rad coolant still nice and blue. will see if cooler blocked when i do the flush. fingers crossed.

update : all works fine for about 3 miles then as temperature settles at norm she stops changing up from 2nd gear and reverse becomes very slippy clutch type of thing. Think maybe its time to ditch this bitch it's had far too much of my folding spent on it. Not what you want to hear folks but maybe i should have kept the old disco

when you changed the fluids , you did manually select all gears on the box and left to run in them for a minute or so to fll the valve block up didn't you?

sure did, tried it several times too. gearbox slips like a cat trying to bury a turd on a tin roof and gear oil gets hot enough to fry chips.
Gonna cut me losses i think, and if i can find a cheap decent GC to replace it then at least i got loads of good spares. If not then i lost a shed load of wedge

isn't a gearbox swap worth a punt?

Under normal circumstances you're probably right, but, to be honest everytime i drive the thing something else goes wrong. I only finished the rear axle rebuild last friday, then saturday the box goes. Shame is , it's got almost 13 months mot left on it
