Product Description
Gearbox - 3 Synchro - Overdrive - TR2-3A - Reconditioned - RW3058R
Ensure overdrive is clean internally before fitting to gearbox, to avoid cross-contamination from dirty oil
Reconditioned exchange gearboxes have different specifications to match your vehicle. Whether you exchange your old gearbox for a reconditioned item, or attempt a rebuild or repair yourself, you must first establish the exact type of gearbox which you currently possess in your TR. The gearbox number is always stamped on one of the lower corners of the bell housing, usually the lower left hand corner, adjacent to where the clutch operating cross shaft protrudes. Genuine Triumph TR gearboxes were numbered with TS (3 synchro), CT, CD, CC or CF (4 synchro) prefixes. These prefixes and the subsequent serial numbers bore little relationship to the commission (chassis) number of the car. To further compound the lottery of what might be fitted in your car, gearboxes from other Triumph sports and saloon models could be fitted directly or adapted to fit - and frequently were. The most commonly discovered anomaly on 6 cylinder TRs is fitment of the overdrive gearbox from the Triumph 'Large Car' 2000/2.5 saloon range. Such fitment does however involve an amount of adaptation on the gearbox, chassis and clutch. Original factory exchange reconditioned units were numbered with the prefix 'GR' and a suffix of '/7', and can be identified by these markings. Overdrive gearboxes were coupled to an 'A' type overdrive, which operated on 4th gear only on TR2s up to TS5979 and on 2nd, 3rd and 4th gears on models thereafter.
Units returned for the exchange reconditioning scheme should as a matter of course be completely assembled, drained of oil and externally clean, with no obvious visual damage. In addition, they should be of identical type to that supplied. Please contact us to determine exactly what is required in return as an exchange old unit (ie less clutch operating ancillaries, adaptor plates etc - see also 'Specification').
Note that non TR old units will incur a surcharge.
Note: We can also offer a customer-own-unit reconditioning service, particularly useful when we have no unit available off the shelf, due to lack of old core.
SPECIFICATION - RECONDITIONED EXCHANGE GEARBOXES AND OVERDRIVES
Exchange reconditioned gearboxes are fitted with new bearings, seals, gaskets, synchro rings, countershaft and have matched internals. All units are fitted with the top cover/selectors but please check that this is compatible with the unit removed from the car (ie switches, wiring, etc). You may need to swap over top covers. Please note that the gear lever, wiring, switches, clutch cross shaft, fork, release bearing carrier, adaptor plate (O/D) and rear extension housing (Non O/D) are not supplies with our units - again, you will need to transfer over from you old gearbox. Exchange reconditioned gearbox and overdrive assemblies are as above supplied less overdrive solenoid, output flange and any mounting bracketry. Depending upon availability, the type of overdrive annulus fitted may differ from original, necessitating recalibration of the speedometer.
