When considering it further and reading about the myriad of other internal stuff that can go wrong with old / worn auto boxes I started thinking that it was actually a bit daft using it for parts and I may as well as just swap it out - down side to this was I would have to swap the 100mm cups for the 90mm on the TJA and accept that the gear ratios wouldn't be quite as leisurely in top - this new one is slightly higher revs but nippier for that. So having swapped the cups the final challenge is what to do about the transmission oil cooler - and this is what I need to be sense-checked.
Based on the knowledge that these boxes don't ordinaily need cooling (in regular cars at any rate - most coolers seem to be in vans and drag cars), initial thoughts were to perhaps somehow block off where the banjo bolts are but discounted as couldn't find reference to anyone else who had done this and would probably interrupt the flow of hot fluid internally (?) - that left 2 options :-
1. work out how to integrate into the water cooling system (but again, can't find and refs as to how to achieve this)
2. do nothing and let the oil flow through the heat exchanger without cooling - I am thinking this last option would be fine in view of the fact that it really doesn't need cooling as far as I know
2 is favourite & least resource hungry but would appreciate your views as to whether my logic is sound here! TIA. Rob
