So you find yourself in the Unfortunate Position where your Engine/Auto Transmission is beyond Economic Repair so maybe buying a Used Replacement is the answer?
But How do you tell the difference?
If its your first A Series Auto it would be all too easy for Somebody to sell you a Manual Engine/Transmission under the pretense that its actually an Auto Unit or Claim that a Manual Engine Block is an Auto
If there was no gear selctor attatched it may not be Aparent which your about to buy?
So What are the main tell tale signs to look for?
Heres a typical A Series Engine with AP Automatic Transmission
Heres a typical A Series Engine with a Manual Transmission
Number 1
Oil Filter Type and Position
The Oil Filter on a Car Fitted with Automatic Transmission is of the old fashioned Purolator type Consisting of a Horizontally mounted metal canister mounted to the Transmission front cover and contains a paper type filter such as Unipart GFE 104 and is shown in the photo below
On Cars Fitted with Manual Transmission the Oil Filter is generally Spin On Disposible Type such as Unipart GFE 443 or GFE 405 or on early models may have a Purolator Canister with a paper filter such as a Unipart GFE 478 and in all cases are mounted vertically on the front of the engine block above the Transmission casing as shown in the photo below
This Mounting Position on Automatic Engines is Either blanked off using a blanking plate secured by two bolts in the case of early Automatic engines or was simply never drilled out on later Auto engines.
Number 2
Dipstick Location
The dipstick on Automatic Transmissions is located on the left hand side of the engine as you look at it from the front just by the Torque Convertor Housing and is generally of a plastic construction as shown in the Photo Below
The dipstick on an Engine with Manual Transmission is located in the middle of the engine block at the front and are of metal construction as shown in the photo below
As in the case of the casting when used on an Automatic Transmission Model you can see the location present on the Automatic engine block but it will never have been drilled out during production.
Number 3
Torque Convertor Housing and Clutch Cover
The Torque Convertor Housing is larger in size and quite Smooth in appearance and look like the Photo Below in which you can also clearly see the dipstick location on Automatic Transmission models
The Clutch Cover on Manual Engines is Smaller on the Manual Engine and has Stengthening Ribs rather than the smooth Appearance of the Torque Convertor Housing as seen in the Photo below
Number 4
Transmission Casing
On Cars with Automatic Transmission the Transmission casing is larger than that of a Manual Transmission and the underside of the casting is ribbed like that of the Manual Casting however it has a seperate front cover that is flat in appearance to which the Oil Filter is atatched to and behind which the Transmission Valve Bodies are housed and is shown in the Photo below
On later models there is a Square box mounted on the Front cover this houses the Starter Inhibitor Switch.
On cars with Manual Transmission the casing is smaller in size and of one piece with no need for a seperate front cover and the Strengthening ribs continue the entire length of the casting from the back and continuing around to the front where the Valve Body Cover would be on the Automatic Transmission casing as shown in the photo below
So now if somebody tries to sell you a Manual Engine or Transmission or the two together claiming its an Automatic you will be able to tell the difference between the two ;D
