nicky Posted July 31, 2017 Share Posted July 31, 2017 Currently sitting on side of the road, autobox won't select drive, 2 or 1 only park and reverse but if I leave it 10-15mins I can get it driving again as long as I don't stop? What could this be anyone? Need help asap, if I can get the car going again when traffic dies down Im going to drop it to whiftbitz (15-20miles away from me) Quote Link to comment Share on other sites More sharing options...
Dnk Posted July 31, 2017 Share Posted July 31, 2017 Have you checked the atf level on the dipstick ? Quote Link to comment Share on other sites More sharing options...
nicky Posted July 31, 2017 Author Share Posted July 31, 2017 Yeah it seems full but I checked it when it had just turned off so I'm letting it cool and checking all levels Quote Link to comment Share on other sites More sharing options...
Dnk Posted July 31, 2017 Share Posted July 31, 2017 What colour is it Quote Link to comment Share on other sites More sharing options...
nicky Posted July 31, 2017 Author Share Posted July 31, 2017 Reddy browny colour Quote Link to comment Share on other sites More sharing options...
Dnk Posted July 31, 2017 Share Posted July 31, 2017 I'm guessing as it's done over 100,000 miles and was juddering when you bought it maybe it didn't like having the extra torque the single has put through it Quote Link to comment Share on other sites More sharing options...
nicky Posted July 31, 2017 Author Share Posted July 31, 2017 Maybe but thought auto boxs were good for 550-600? I'm only on 525 at moment (can't remember torque figures) Quote Link to comment Share on other sites More sharing options...
Rob W Posted July 31, 2017 Share Posted July 31, 2017 Has it got coolers on the box? It's the heat and torque that kills the boxes, guessing you must be around the 480-500ftlb. Some cars on auto boxes have lasted with extra coolers and correct ducting, some others haven't. Quote Link to comment Share on other sites More sharing options...
Burna Posted July 31, 2017 Share Posted July 31, 2017 Maybe but thought auto boxs were good for 550-600? I'm only on 525 at moment (can't remember torque figures) Yeah the torque will be the figure to look at, but any extra power you should have extra cooling on the auto box, what coolers have you got and where?

Dnk Posted July 31, 2017 Share Posted July 31, 2017 (edited) It has 2 coolers according to the spec but the box has done 100k + so already a fair bit, some will last longer than others when you slap a single on, controlling the change helps but doesn't look like this car has Syvecs or similar I drove a bpu auto tt recently and the box was starting to slip, that was on similar mileage to Nicky's Edited July 31, 2017 by Dnk (see edit history) Quote Link to comment Share on other sites More sharing options...

Dnk Posted July 31, 2017 Share Posted July 31, 2017 How can you tell a box is slipping? Can be hard to tell until gets more obvious but this one felt like it had a delay or a pause, fluid didn't look great either Quote Link to comment Share on other sites More sharing options...
nicky Posted July 31, 2017 Author Share Posted July 31, 2017 It's weird I just took a long drive to garage whiftbitz and I've just arrived, a 30minute journey turned into an hour journey had to stop 10 times or more The revs would just drop and it would slip out of gear, then the only gear that actually works is park They open at 11 on London branch so we shall see what he thinks.

Dnk Posted July 31, 2017 Share Posted July 31, 2017 (edited) I'd be dropping the sump off and seeing how much sludge etc is in the box/strainer/filter, this is the tt box with the sump pan removed showing the strainer/filter in place Edited July 31, 2017 by Dnk (see edit history) Quote Link to comment Share on other sites More sharing options...
Tsia Posted July 31, 2017 Share Posted July 31, 2017 Same problem for me the other week with my single turbo auto, was the box overheating because it hadn't properly been cared for, so I've got a fresh box and had DavidP work his magic on it, replaced the strainer and looking to get it in the car next week or so. I'm on my phone at the moment so can't link it, but check out the A340E transmission group (can find it via my profile) - it'll have the answers to pretty much everything auto related.

evinX Posted July 31, 2017 Share Posted July 31, 2017 Its good for 550-600 with slight mods. The fluids probably done in and needs flushing. Also you check the level woth engine running and in neutral Quote Link to comment Share on other sites More sharing options...
Tsia Posted July 31, 2017 Share Posted July 31, 2017 Thanks Frank. With mine, it was working perfectly at lunch time, but felt like it was slipping on the way home. Eventually, the gears wouldn't engage at all. If I stopped the car for 5 mins to let it cool, I was able to crawl it a bit further - though in doing so I have knackered the box. Thankfully TT autoboxes aren't too pricey, and it gave me chance to get the new one shimmed up by David Edit: Reverse wouldn't select on mine after I crawled it back. At first, it did, but then dropped off after a while :/ Quote Link to comment Share on other sites More sharing options...

As I may just start looking for a boostlogic box to handle a bit more power Quote Link to comment Share on other sites More sharing options...
Tsia Posted July 31, 2017 Share Posted July 31, 2017 £200 for a known good working box. If you join the group, any well priced autoboxes that are found are posted up on there Quote Link to comment Share on other sites More sharing options...
Frank Bullitt Posted July 31, 2017 Share Posted July 31, 2017 No need to fork out for a Boostlogic box, one of DavidP's hybrids should suffice. Also iirc the Boostlogic give a nice thump when you put the car into reverse. Quote Link to comment Share on other sites More sharing options...

If you join the group, any well priced autoboxes that are found are posted up on there I've since spent a few quid on new fluids and a few parts to keep it running sweet, but still a lot less than a boostlogic box!
