1500 o/d gearbox problems

[mpbarrett]

if the clutch is not releasing you could try pumping the pedal it as this sometimes helps to get a bit more movement in the hydraulics and disengage the plate, and then try changing gear.

If that helps it points to a clutch hydraulic problem.

Errr lets get this right,

ye say cant go in or oot of gear,correct.

 

yer think,n its clutch, correct

 

well, ye dont need a clutch t,change up or doon the box

clutch wont stop a gear lever  shift,n between gears

 

noo if it wer crunch,n whenst going into gears, then thats a clutch problemo

providing that yer syncros aint worn doon

 

basicly, ye can go up doon box ont move wid nee clutch

just a matter of timing changes right

 

Its most likely int inner links inside top oft box

real pain in the but t,wurk on them stupid 1 rails

They didn't. The Toledo had a 3-rail while the Mk4 Spitfire was in production, with the same 3-rail. The Dolomite also had 3-rail at that time. From about the start of 1500 Spitfire production on, all Toledos and Dolomites (except the Sprint) got single-rail gearboxes, too.

The change over (Standard 8 based gearbox) with small Triumphs to single rail was around 1974/5. The (not counting the FWD models) Toledo was introduced in 1970, the Dolomite 1850 in 1972 and the 1500TC RWD in 1973. The 1300 and 1500  Dolomite were introduced in 1976, the Toledo and 1500TC RWD were dropped at that stage. The UK Mk4 Spit in 1970-1974 and the UK 1500 Spit in 1975. (The US 1500 Spit Nov 1974)

The early TR7 was also fitted with the single rail gearbox, Dolomite 1850, as there were insufficient five speed gearboxes available.

Basically anything made after Oct 1974 should have been fitted with the single rail gearbox. Anything  before that date the three rail gearbox. 

The Sprint was introduced in 1973 but used the Big Saloon/TR gearbox (Vanguard based gearbox).
