carl0s Posted March 18, 2004 Share Posted March 18, 2004 I have been presuming this is quite normal, since the box engages while there's some (idle) power going through it. Anyhow, engaging R or D gives a short 'thud'. It is normal, right? Link to comment Share on other sites More sharing options...
Paul R Posted March 18, 2004 Share Posted March 18, 2004 Sounds normal to me. My old auto used to do the same. Paul. Link to comment Share on other sites More sharing options...

paul mac Posted March 19, 2004 Share Posted March 19, 2004 you may want to check you fluid level, when i first got the soop i had a local garage change all fluids and after a month or so it started to "thud" quite dramatically especially going from reverse to drive, i then found out via the site how to check the level corectly and found the garage had overfilled by about a litre and a half, i drained the excess and changed the rest for the pukka toyo fluid and it sorted it, however it has started to do it again and i can also feel it thuding a bit when it changes down sometimes so i'me wondering if the overfill has damaged it - beware Paul M Link to comment Share on other sites More sharing options...
Terminator Posted March 19, 2004 Share Posted March 19, 2004 AFAIK over filling is bad news for an auto box especially if you dont know and drive it hard. Paul 1.5 lt extra is quite a bit. Do you know what fluid they put in? It is suprising how many garages do not know how to test the fluid level or what fluid to use. When ever I do a auto box fluid change. I do a level check before draining, drain the fluid and measure how much has come out. Refill with the same amount that came out, take the car for a gentle run to warm the fluid through then chenck the level again and do a final top up if necessary. There is quite a bit of drag from a cold box, especially as you are on high tickover as well. It should be less noticible when it reaches operating temperature.

paul mac Posted March 20, 2004 Share Posted March 20, 2004 thanks termy yer your right about garages not knowing how to check the fluid in the end up i did it myself, the cars going into a auto transmission specialist on monday, who are going to do a service on it, sump cover off, line pressures,leaks, solenoids (i got lost after that) he seemed quite positive and did'nt think it was quite the end of the box (yet) i'll post any findings Link to comment Share on other sites More sharing options...
Terminator Posted March 20, 2004 Share Posted March 20, 2004 The box is very strong. But putting thwe wrong fluid in can ruin seals and other componants. Make sure the specialist has delt with the box before. There are few auto box specialists recommned on here. Get in touch with Chris Wilson and ask his advice, it might save you loads.
