diesel dave Posted September 1, 2007 Share Posted September 1, 2007 hi all. this is my first post (of many i suspect) so please bear with me. i have a 1994 soft dash vogue 300tdi auto, which i bought 4 weeks ago. I subsequently found that it changed down of its own accord at 70mph. i only had a week before going to france in it for a fortnight, so i bought another 4hp22 gbox secondhand, and fitted that. i did find that the replacement box was slightly shorter than the original gbox (the difference being in the length of the govenor housing at the rear). after modifying the mounting holes and the front prop the box fitted fine, and works well. the problem is the transmission tunnel gets really hot inside the car, especially the cubby box and around the electric window switches. i have just done over 1000 miles in the last two weeks with no obvious adverse effects. i was wondering if there is normally some sort of insulation above the gbox, or if it may be a problem with the transfer box now it is mated to a v8 gbox. i changed all oils etc before going away, and kept a close eye on engine oil and gbox fluid while away. all levels remained constant. all replies gratefully received Quote Link to comment Share on other sites More sharing options...
geoffbeaumont Posted September 1, 2007 Share Posted September 1, 2007 Can you compare it with a similar vehicle (automatic - not necessarily diesel)? They do get quite warm along there, so I'm guessing it's nothing to worry about. Quote Link to comment Share on other sites More sharing options...
Bowie69 Posted September 1, 2007 Share Posted September 1, 2007 My 1991 RRC V8 Auto gets pretty hot -the carpet on the side of the transmission tunnel is lovely and warm Quote Link to comment Share on other sites More sharing options...
bishbosh Posted September 2, 2007 Share Posted September 2, 2007 "Pinch" the gear stick at its base. If it is too hot to comfortably keep your fingers there then it is too hot. All my auto boxes (both V8 and TDi) have made the gear stick very hot, but I could still keep my fingers on the stick and I definately don't have asbestos hands - I drive a desk for a living! Not exactly a scientific test, but it will give you an idea. Also, do all your warning lamps work? if the autobox coolant warning light doesn't come on then you should be OK.

paintman Posted September 2, 2007 Share Posted September 2, 2007 Tunnel on my 86 auto also gets hot on long journeys. Esp when towing. But it has done that since I bought it in 1994 so appears to be normal. Quote Link to comment Share on other sites More sharing options...
NickSuzy Posted September 4, 2007 Share Posted September 4, 2007 The transmission tunnel on my old SE used to get so hot it turned it funny. It went all hard and horrible. Never found out and is still the same with the new owner. Nick Quote Link to comment Share on other sites More sharing options...
