    I was curious to know what was the last year for full size Diesel Blazer/jimmy and what tranny did they put behind those. A freind said they put some in the new style(ifs) But I have never seen one , I am more curious on the classic old style. Was 1990 the last?

    The last year for diesel K5's was the last year for K5's, 1991. They came with either the SM465 4 spd or the 4L60 tranny.

    Even though it didn't carry the Blazer name, the Tahoe (same truck, diff. name) in 2 door form had a 6.5 until 1999.

    In 1991 was the auto tranny a 4 or 3 speed and what transfer case was behind it. I have an '86 Diesel Blazer with TH400 and 208, and I want a 4 speed auto.

    Good Luck. The only 4speed autos are the TH700R-4 and the 4L60E, which are the same tranny, except that the latter has electronic controls. It is generally understood that these are about on par with a TH350 when done right, but they are not as strong as the TH400.

    Here are some key questions:
    -What transmission is the 6.5 TD usually mated to?
    -Is this tranny a 3 or 4 speed?
    -What kind of adapters are needed to mate this tranny to a 6.2?

    I have a '90 K5 with the 6.2 and it is backed by a 700r4 (aka 4L60)and a NP241 case. To the best of my knowledge, the civilian models back to at least '86 were equipped with the 700r4 except for the military CUCV versions which I believe had the TH400.

    The 6.2's also have the same bellhousing as the gas engines so they should interchange, transmission wise, fairly easy.

    I know the 6.5 turbos were available with the 4L80 in the 3/4 and 1 ton trucks, though I'm not sure if either the 4L80 or the 4L60 was used in the Tahoes or not.

    -What transmission is the 6.5 TD usually mated to?
    If it's automatic, then a 4L80E is used. If the vehicle is stick, then a 5-speed (MW3 option) trans. is used.

    -Is this tranny a 3 or 4 speed?
    They 4L80E is a 4-speed automatic.

    4 -&gt; 4-speed auto
    L -&gt; Longitudinally mounted (a.k.a. "The Long Way")
    80 -&gt; Model Designation
    E -&gt; Electronic shift Transmission

    -What kind of adapters are needed to mate this tranny to a 6.2?
    I would assume no adapters would be needed. GM uses a 6.5 as a direct replacement for the 6.2, since 6.2s are no longer made. Should directly bolt in.
