Richmac Posted April 23 Report Share Posted April 23 Hi after looking for a while for a nice tr4 I have found one I like but its not fitted with an overdrive gearbox something that was high up on my list of wants. So my question is how much would it roughly likely cost to change the gearbox for an overdrive type with all of the associated wiring? I'm looking at just giving the car to a specialist to carry out the work and assuming all parts are available of the shelf... Or am I being delusional? Advice appreciated regards Richard Quote Link to post Share on other sites
RogerH Posted April 23 Report Share Posted April 23 Hi Rich it may be worth talking to whoever you think will do the fitting. It would be north of £2K You could get an unknown GB&OD for £500+ then spend £500 to overhaul each item = +£1500 Fitting £500+ Speak to Tom Cox - this is what he does Roger Quote Link to post Share on other sites
John Morrison Posted April 23 Report Share Posted April 23 Agree with Roger If you’re going to specialist s then at least 2K. John Quote Link to post Share on other sites
trchris Posted April 23 Report Share Posted April 23 As comments above an overhauled gearbox alone is going to be around £2000 then clutch/ associated wiring/ switches and labour on top so nudging £3000 ish Chris Quote Link to post Share on other sites
Lebro Posted April 23 Report Share Posted April 23 Just in case you don't know, the gearbox mainshaft has to be changed to a shorter one, which means a complete gearbox strip down. Bob Quote Link to post Share on other sites
Richmac Posted April 23 Author Report Share Posted April 23 Thanks guys for your input. I looked on Pete Cox website and can see rebuild costs. I think I have enough info for the moment to make a decision Thanks again for prompt replies Richard Quote Link to post Share on other sites
Besalu Posted April 25 Report Share Posted April 25 I bought a A type overdrive gearbox and all the associated bits and pieces off Tom Cox for my 4a. Highly recommended. Richard Quote Link to post Share on other sites
Richmac Posted April 25 Author Report Share Posted April 25 Thanks Richard however the car I was interested in was at auction and I didn't bid enough to win it. The search continues Quote Link to post Share on other sites
