Auto gearbox – slow to engage, clutch slip

The car was manufactured with a Borg Warner 35 auto gearbox. I think the same unit is still in the car. With the car running, reverse selects OK, but drive (especially first) may not engage initially in D or 1. Applying some revs has either no effect or drive is suddenly acquired with a jolt that can spin the rear wheels – not pleasant.


After some superficial forum research it sounded like a simple lack of fluid. On checking the dip stick – nothing - not a trace on the stick. Off to the local motor factors, but no one locally stocks ATF without Dexron. So back to the interweb and wait for delivery.

 There seems to be two ways of checking the fluid level before topping up:
a) Start the engine and run the selector through all drive settings, then quickly dip and fill to the lower/cold mark
b) Start the engine and drive the vehicle until warm making sure that all drive settings have been used. Park up on a level surface and quickly dip and fill.

As mine was being a little temperamental I went with (a) to start with. It drank about 300ml before it was seen on the  bottom of the dip stick. I will do (b) the next time I go for a run.

Fuel pipe into DS carb not connected

Image
On inspection I noticed that the fuel pipe to the drivers side carb has sprung off the carb and was hanging free. The car must have been running on a single carb for the last few miles home. That would explain the loss of power when driving back. Replaced the pipe and re-connected - tighter this time.

More Electrical Gremlins

Image
As you may have read from my previous posts, a historical rebuild / refurb of this car has introduced some electrical gremlins. Whilst investigating why the battery totally discharged every few days I noticed that there was considerable spurious wiring hanging out of the dash for a) a radio which wasn't fitted b) a rocker switch fixed to the centre console for something or other - unknown. There was also missing bulbs in the dash and issues with non functioning interior lighting, not to mention a random indicator that seems to make it's own mind up whether it works or not. So whilst I was waiting for some paint to dry I decided to investigate and remove the spurious wiring.  Got a little carried away. Now it's all in bits I will put it back together with a little more care than the last time, check and test all of the wiring and replace with LED in the dash and interior - might even do the the indicators as well. The more I look into the electricals the more I need

Alternator Problems

Image
I t's been a few weeks since I have had any time to work on the Stag. It's been a very busy time at work - the culmination of 2 years work successfully delivered at the end of June 17. So now it's time to take a breath and get back into the garage. The last few weeks have benefited from some very warm, dry weather - perfect for the old Stag. I have had the Stag on the road a few times with the hood down listening to that intoxicating burble. But, every time I get into the car after it has stood for a few days, the battery is flat. As there is now radio or clock at the moment, then this is a little puzzling. Once started the, voltage reading climbs up to 16.5v (as I would expect if the battery was very low) but it stays there and doesn't drop back as I would expect after 20-30 miles. Dropped a quick query on the SOC Forum and the consensus is that the alternator needs replacing. The built in regulator is probably not functioning.  The direct replacement is the 18 ACR.
