T25 Auto Gearbox Issues (Newbie)
Posted: 26 Aug 2020, 13:26
Hi All,
Recently bought a 1985 T25 1.9L with an automatic gearbox. About 52,000 miles on the clock.
Van was running smoothly until last week when I took it to Wales from London.
After a day's driving followed by another morning of driving I started up the engine and found that the gears were slipping. I parked up the van and called a towing service who suggested topping up the transmission with some oil after finding it was empty. He only had a small amount of transmission oil but it got the van running smoothly again. He suggested we add another 1 litre of transmission fluid when we could.
The van was running smoothly for about 45 mins of driving as we went off to find more transmission fluid. We stopped the car while looking for fluid. We were told to head further down the road and then after starting up again I was getting the same issues as before with slipping gears. The van was only moving at around 20 MPH tops.
After taking a taxi to get transmission fluid we topped up with 1L of fluid but not much luck with getting the van to run above 20MPH once again.
As things stand the van reverses and moves forward but I don't know how fast it will drive at the moment - haven't tried it for a week or so.
I have taken it to a mechanic who seems to want to take the thing apart and charge a lot of money for it.
I have spoken to the dealer who I bough it off (also a mechanic) who suggested a much cheaper first step of changing the filter and the oil and seeing if that might help.
Another mechanic I spoke to over the phone suggested seeing if there were any oil leaks coming out of the transmission and seeing if fixing that might help solve the issue.
I am a complete amateur with regards to all of this and I'm just looking for any advice from anyone with knowledge on the subject.
Appreciate it
Alex
